Gamma-Butyrolactone GBL

Gamma butyrolactone is a chemical. People use it as medicine. Be careful not to confuse gamma butyrolactone (GBL) with gamma hydroxybutyrate (GH).despite serious safety concerns and illegality, people take gamma butyrolactone for improving athletic performance, sleep, and sexual performance and pleasure. They also take it for relieving depression and stress, prolonging life, promoting clear thinking, causing relaxation, and releasing growth hormone. GBL is also used to trim fat and as a body- or muscle-builder. Some people take it as a recreational drug.

GBL is a lactone. It is hydrolyzed under basic conditions, for example in a sodium hydroxide solution intosodium gamma-hydroxybutyrate, thesodium salt of gamma-hydroxybutyric acid. Under acidic conditions it forms an equilibrium mixture of both compounds. These compounds then may go on to form a polymer. When treated with a non-nucleophilic base, like lithium diisopropylamide, GBL can become an alpha-carbon nucleophile. The related compound caprolactone can be used to make a polyester in this manner.GBL is not active in its own right; its mechanism of action stems from its identity as a prodrug of GH.
