What is GBL(gamma-butyrolactone)?


Gamma-butyrolactone (GBL), a chemical used in industry, is a precursor to and illegal alternative for gamma-hydroxybutyric acid (GHB).

Because GBL and 1,4-butadiene (BD) share structural similarities with GHB,

there is evidence that these compounds are transformed to GHB when taken orally.

Schedule I depressants include GHB. Teens and young adults began abusing GHB in dance clubs and “raves”

in the 1990s, and gained notoriety as a date rape drug.

gbl can also be defined as

Gamma-Butyrolactone, or GBL, is a colorless, water-soluble liquid that is hygroscopic and has a faint distinctive odor.

The simplest 4-carbon lactone is this one.

It is primarily employed as a chemical building block in the synthesis of other substances, such as methyl-2-pyrrolidone.

GBL is used as a recreational CNS depressant in humans, where it functions as a prodrug for gamma-hydroxybutyric acid

(GHB) and has effects akin to those of barbiturates.


Extracts from samples of unadulterated wines have been confirmed to contain GBL.

According to this research, GBL is a naturally occurring substance that can be found in some wines and possibly other items.

Using a straightforward extraction method and GC/MS measurement, the concentration of about 5 g/mL was easily observed.

GBL can be detected in cheese flavorings, however the final food product normally contains only 0.0002% GBL.

How is GBL made? or What is GBL made out of?

Production and Synthesis

Industrial production of -butyrolactone involves dehydrogenating 1,4-butanediol at temperatures between 180 and 300 °C at atmospheric pressure while using a copper catalyst.

Dehydrocyclization of 1,4-butanediol to form γ-butyrolactone in the presence of a copper catalyst

This method has a 95% yield on average. An extraction using the liquid-gas phase is used for purification.

It can also be made in the lab by oxidizing tetrahydrofuran (THF), perhaps with aqueous sodium bromate.

An alternate pathway leaves GABA and travels through a diazonium intermediate.


GBL is hydrolyzed into sodium gamma-hydroxybutyrate, the sodium salt of gamma-hydroxybutyric acid, when it is exposed to basic

conditions as a lactone. An equilibrium between lactone and acid forms can be found in acidic water.

The polymer poly(4-hydroxybutyrate) and the dimer 1,6-Dioxecane-2,7-dione may then be created from these molecules.

When GBL is exposed to a non-nucleophilic base, such as lithium diisopropylamide, the alpha carbon atom deprotonates to the carbonyl.

This method allows for the production of polyester from the related molecule caprolactone.


Poly Butyrolactone is produced when butyrolactone undergoes ring-opening polymerization.

The product undergoes heat cracking to return to the monomer.

It is asserted that poly(GBL) and the commercial biomaterial poly(4-hydroxybutyrate), or P4HB, are competitive.

Even though both materials are generated from nature, it is further asserted that poly(GBL) is less expensive to produce than P4HB.

What is GBl used for? or What are the common uses of gbl?

The main use of butyrolactone is as a precursor to other compounds.

NMP and pyrrolidone are produced by reactions with methylamine and ammonia, respectively.

Additionally, certain polymers and lotions employ it as a solvent.

Because of its wide liquid range, chemical stability, and high dielectric constant, butyrolactone is utilized as the organic solvent in electrolytic capacitors. To change internal resistance, it is typically used with ethylene glycol in a modest ratio—”9:1″ is a typical combination.

In a variety of scientific studies, including the creation of methylammonium lead halide, it has been utilized as a solvent.

In humans

GBL is used as a recreational CNS depressant in humans, where it functions as a prodrug for gamma-hydroxybutyric acid (GHB) and has effects akin to those of barbiturates.

legal uses

Gamma-butyrolactone is a widely used industrial chemical solvent and intermediate that is

present in nail polish removers, cleansers, adhesives, and paint removers.

The amount of GBL produced globally is measured in hundreds of thousands of metric tons.

Illegal uses

GBL is abused because of its euphoric and sedative properties.

GBL is mostly self-administered, with a recreational oral dose of 1 mL being the most common.

When opposed to GHB, GBL has a faster start of effects and a longer duration.

Gamma-Butyrolactone (GBL) is widely used in industry. It is a solvent that is commonly found in paint strippers, nail polish removers, stain removers, and circuit board cleaners.

It is also used as an intermediate in industrial chemistry, such as the production of pyrrolidones, and in some medications.

Despite major safety issues and the fact that it is illegal, some use gamma butyrolactone to improve sports performance, sleep, sexual performance, and enjoyment.

They also use it to treat depression and stress, to lengthen life, to promote clear thinking, to relax, and to release growth hormone.

GBL is also utilized as a fat burner and a muscle builder. Some people use it for recreational purposes.

More industrial uses of GBl Gamma-butyrolactone

According to the publisher, the global Gamma-Butyrolactone market would rise at a rapid pace over the anticipated period.

The global Gamma-Butyrolactone market is being driven by factors such as general usage of Gamma-Butyrolactone

in the electrical and agrochemical industries.

In the agrochemical industry:

GBL is utilized as a parent chemical to make herbicides and as a plant growth regulator.

Its low freezing point and high boiling point make it an excellent raw material for the electrical industry.

As a result, it is employed in batteries as well as other solvents. Furthermore, its use in the dyeing and

pharmaceutical industries is likely to grow.

However, the availability of replacements in practically every industry, as well as the abuse use of GBL as a narcotic,

has forced all countries to control its market flow.

As a result, the Global Gamma-Butyrolactone GBL market may be restrained over the forecast year.

Gamma-Butyrolactone is mostly manufactured in liquid form and is also used in the production of herbicides, capacitors as an intermediate in the production of pyrrolidone, circuit board cleaners in electronics, paint strippers, and nail polish removers.

It’s also a cellulose acetate, polyacrylonitrile, and polystyrene solvent. Gamma-Butyrolactone has pharmaceutical applications such as producing relaxation, boosting mental clarity, improving sexual performance, lowering fat, and improving sleep.

However, because the chemical can be used as an abuse drug, most nations throughout the world have nearly outlawed or highly controlled its medical uses.

The agriculture industry:

It is the largest consumer of Gamma-Butyrolactone and is projected to remain so for the foreseeable future.

According to the World Health Organization (WHO), the worldwide population is predicted to exceed 8.2 billion by 2026, dramatically increasing global food demand.

Herbicide consumption exceeded 1.2 million tons in 2018, increasing demand in the Gamma Butyrolactone sector.

The US accounts for more than one-third of the global herbicide industry, making it a promising potential market for Gamma-Butyrolactone.

Humans’ reliance on technology is increasing as the world population grows; as a result, it is difficult for any sector to operate without computers and other electronic devices and gadgets.

As a result, the growing demand for computers and other electronic devices that rely on tiny capacitors has boosted the Global Gamma-Butyrolactone (GBL) Market.


The growing usage of batteries and capacitors in the vehicle sector, as well as the shift away from petroleum and toward batteries, are driving the Gamma-Butyrolactone market.

Gamma-Butyrolactone production and commerce on a global scale is in the hundreds of thousands of metric tons.

The US alone generates approximately 185, 000 metric tons of Gamma-Butyrolactone. Gamma-Butyrolactone is a polar solvent that is commonly employed with ionic substrates.

It functions as an acid donor in aqueous environments at high temperatures, making it extremely helpful for the chemical sector and driving the GBL market.

Almost half of all Gamma-Butyrolactone produced globally is used to make Tetrahydrofuran (THF), the compound’s main derivative.

TFH is a great solvent for surface coating, film casting, printing inks, and adhesives.

Gamma-Butyrolactone is also utilized in the production of graphic films, and it can be employed as a lithography developer by rapidly removing and dissolving partially polymerized

photochemically active polymer that has not been exposed to ultraviolet light (negative image) or cured UV damaged coating (positive image).

As a result, Gamma-Butyrolactone can be employed in photography as a dispersant and as a finishing agent.

Uses of GBL in medicine,


The body’s own natural process easily converts GBL to GHB. As a result, GBL has a similar

GHB has pharmacological effects. GHB is found in very low amounts in the central nervous system; it is a metabolite of the neurotransmitter gamma-aminobutyric acid (GABA).

gamma hydroxybutyrate may act as a neurotransmitter or neuromodulator in the brain, according to scientific evidence.

It has dose-dependent depressive effects similar to barbiturates and methaqualone. GBL/GHB at low doses causes drowsiness, nausea, and visual distortion.


Blood-borne paraoxonase (lactonase) enzymes quickly transform GBL into GHB.[15][16] Animals lacking these enzymes do not experience the effects of GBL.

Since GBL has a higher bioavailability and is more lipophilic (fat soluble) than GHB, it is absorbed more quickly.

Due to these pharmacokinetic variations, GBL tends to be somewhat more potent and quicker to take action than GHB, but 1,4-butanediol

(1,4-B), a similar molecule, tends to be slightly less potent and take longer to take effect than GHB.

nutritional augmentation:

Sports and athletics Gamma-Hydroxybutyric_Acid
Due to its ability to act as a prodrug of GHB and boost GH secretion associated with sleep, GBL was marketed as a nutritional supplement after GHB was scheduled under the trade names Revivarant and Renewtrient until they were outlawed by the FDA.

medication used for fun

GBL is a prodrug of GHB, and as such, its use for recreational purposes is solely due to this.[20] An overdose of GBL may result in illogical behavior, serious illness, coma, or even death.

Home synthesis kits for converting GBL and/or 1,4-B into GHB were introduced to get around GHB restriction legislation.

confiscated GBL bottles

FDA warning about GHB and related prodrugs, including GBL GBL has a peculiar flavor and odor that has been compared to burnt plastic, fake melon, and stale water. Compared to GHB, which is said to have a noticeably “salty” taste, this is very different.

GBL has gained a lot of popularity among young people in French nightclubs as a result of the ease with which those with little knowledge of chemistry may produce it using simple to obtain precursors.


GBL can irritate the stomach and esophagus when taken orally undiluted. Oral consumption of GBL has the potential to produce nausea and other related issues, possibly more so than GHB.

The effects of GHB are biphasic, with euphoric effects at low dosages (thus the name “liquid ecstasy”) and sedative effects at larger levels. This sedation may result in unconsciousness as a result.

A considerable risk of death occurs from the increased sedation and risk of vomiting when taken with alcohol. As a result, several harm reduction organizations advise against combining the two medications.

Numerous GBL-related deaths have been reported in the news, most frequently when combined with alcohol or other depressants.

Gamma-Butyrolactone is frequently used as a date rape drug.

Dependence and addiction

Even when used often over an extended period of time and in moderate doses, GHB or GBL do not appear to significantly increase physical dependence in the majority of users.

For many people, giving up drugs or temporarily abstaining from their use is accomplished with little to no difficulty. However, physical and psychological dependence can arise when consumption is severe and dosages are frequent.

When managing GBL dependence, it is important to take into account the patient’s age, comorbidities, and the GBL’s pharmacological pathways.

Users of GHB and GBL can adopt a “24/7” dosage schedule.

In this situation, the user has grown resistant to the effects of the drug and has upped dosage and dosing frequency purely to stave off withdrawal symptoms.

When users stop using GHB or GBL, they may have withdrawal symptoms, which depend on the amount and duration of usage of the substance.

While excessive, continuous usage can result in severe withdrawal symptoms resembling Benzodiazepine withdrawal syndrome (BWS), light to moderate users frequently report insomnia and sleep-related issues.


The typical form of NaGHB is equivalent to 1.65 g per milliliter of pure GBL, hence doses are measured in the single milliliter range and can be consumed all at once or over the course of a night.

GHB/GBL overdose

GBL/GHB overdose can cause:

  • unconsciousness
  • seizures
  • reduced heart rate
  • severe respiratory depression
  • decreased body temperature
  • vomiting
  • nausea
  • coma
  • or death at large doses.

GBL/GHB consumption over time can lead to addiction.

Chronic GBL/GHB misuse results in a withdrawal state defined by;

  • insomnia
  • anxiety
  • tremors
  • significant autonomic activation (i.e., elevated heart rate and blood pressure), and sometimes psychotic thoughts.

There is currently no antidote available for GHB overdose.

Users population

GBL’s intoxicating qualities lead to usage as a GHB replacement. Teenagers and young people misuse GBL/GHB as an alcohol substitute, at all-night gatherings and “raves,” and to enhance their sex.

There were 151 reports of GBL in 2020, 148 in 2021, and 85 in 2022, according to the DEA’s National Forensic Laboratory Information

System (NFLIS) Drug database, which compiles scientifically verified data on drug items and cases submitted to and analyzed by participating federal, state, and local forensic laboratories in the United States.

Is GBL legal in the US?

Control status

The Controlled Substances Act regulates GBL as a List I substance.Schedule I of the Controlled Substances Act (CSA) prohibits GHB.

GBL and BD are structurally related to GHB, and there is proof that they are transformed into GHB when taken orally.

In an effort to avoid violating local, state, and federal prohibitions, GBL and BD have been sold and used in place of GHB.

According to 21 U.S.C. 802(32)(A) and 813, both GBL and BD may be classified as “controlled substance analogues” under the CSA if they are meant for human consumption.

In the United States (US)

GBL is restricted as a List I controlled chemical in the United States. If intended for human consumption, it is also classified as a controlled substance under Schedule I of the Controlled Substances Act as a GHB analog.

This product’s sales and distribution for industrial use are strictly controlled, necessitate quantity tracing, lock and key storage, and round-the-clock supervision, and are only permitted from a very small number of suppliers who have the necessary DEA registrations, which as of 2021 only included Ashland, BASF, and Miami Chemical.

According to reports, Lyondell no longer sells this product commercially because of increasingly stringent rules and liabilities, but they still produce it for use in internal and downstream operations.

You need a special DEA license and end use certificate in order to buy this substance.

United Kingdom (UK)

Regulation 4B of the 2001 regulations makes it legal to import, export, produce, supply, offer to supply, or possess GBL and 1,4-BD due to their legitimate uses,

with the exception of situations in which someone does so with knowledge or reasonable belief that they will be consumed by humans.

Otherwise, it is a controlled substance of class B.


GBL is categorized as a substance that poses a risk to health rather than as a drug. Although recently passed legislation that will go into effect on 1 April 2011 will allow for the handling of drugs for industrial uses will allow for the classification of GBL and 1,4-Butanediol as controlled substances.


GBL was designated as a psychoactive drug on February 22, 2012. Its trafficking is restricted, and any unauthorized sale, purchasing, or other use is punished by up to 20 years in prison.


GBL falls under the drug category. Manufacturing, processing, reworking, importing, and distribution of GBL all require a license.


In Canada, GBL is listed on Schedule VI of the “Controlled Drugs and Substances Act” as a controlled substance. Vendors are required by Schedule VI of the “Controlled Drugs and Substances Act” to gather data on GBL purchases.

The Act also outlaws the import and export of Gamma-butyrolactone, defining it as either a crime punishable by an indictment with up to 10 years in jail or an offense punished by summary conviction with up to 18 months in prison.

The possession of GBL by a person is allowed in Canada.

What is GBL trafficking?

Gamma-butyrolactone is also referred to as GBL or “coma in a bottle.” Although it was developed as a pain reliever, it is now illegally and recreationally used to induce a high. Additionally, it causes ferocious spasms and is moderately harmful because GBL is simple to overdose on.

Sports and athletics Gamma-Hydroxybutyric_Acid
Due to its ability to act as a prodrug of GHB and boost GH secretion associated with sleep, GBL was marketed as a nutritional supplement after GHB was scheduled under the trade names Revivarant and Renewtrient until they were outlawed by the FDA.

Gamma-hydroxybutyrate (ghb) is more commonly referred to as “liquid ecstasy,” “Georgia home boy,” “grievous bodily harm,” “salty water,” “somatomax,” “easy lay,” “cherry menth,” and a variety of other misleading labels in the gym and on the street.1 The substances in Revivarant, Revitalizer, Blue Nitro, and Weight Belt Cleaner are transformed by the body into GHB.

Bodybuilders assert that GHB enhances their performances by producing growth hormone, promoting sound sleep, and accelerating the breakdown of fat.

Others take GHB to:
  • suppress appetite
  • promote sleep,
  • or elicit euphoria.

GHB is known for being used in “date rape” drugs and during rave parties for its supposed aphrodisiac and disinhibitory effects.

A growing number of partygoers and athletes who have passed away or had major negative side effects from GHB and related substances serve as an example of GHB’s other deadly side.

NBA basketball player Tom Gugliotta of the Phoenix Suns took gamma-butyrolactone (GBL), which the body quickly converts to GHB, in December 1999.

His respiratory failure nearly took his life.

Like Gugliotta, the fortunate ones wind up in emergency rooms where recovery is frequently quick and complete, giving the impression to uninformed bystanders that medical assistance is not required if someone passes out after using GHB.

Clinicians should be aware of this risky supplement due to the serious repercussions of casual GHB use and the necessity of quickly responding to its negative effects.
