What products contain GBL?


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 has a molecular weight of 86.09 g/mol and the chemical formula C4H6O2. It has an oily, colorless consistency and a bitter flavor. Pharmacology: The body’s natural processes easily convert GBL into GHB.
