Gamma Butyrolactone GBL for Addictiveness and dependence CAS 96-48-0 C4H6O2

 

 

Description

 

GBL is rapidly converted into GHB by paraoxonase ( lactonase ) enzymes, found in the blood. Animals which lack these enzymes exhibit no effect from GBL. GBL is more lipophilic ( fat soluble ) than GHB, and so is absorbed faster and has higher bioavailability. Because of these pharmacokinetic differences, GBL tends to be more potent and faster-acting than GHB, but has a shorter duration; whereas the related compound 1,4-butanediol (1,4-B) tends to be slightly less potent, slower to take effect but longer-acting than GHB.

 

The levels of lactonase enzyme can vary between individuals, meaning that first-time users can show unpredictable results, even from small doses. In many this manifests as slow onset of effects, followed by headaches, semi-consciousness which is distinct from GBL sleep in normal users. If the user decides to try again at a later date, they appear to be able to enjoy the effects normally

 

 

Reactions

 

As a lactone, GBL is hydrolyzed under basic conditions, for example in a sodium hydroxide solution into sodium gamma - hydroxybutyrate, the sodium salt of gamma - hydroxybutyric acid. In acidic water, a mixture of the lactone and acid forms coexist in an equilibrium. These compounds then may go on to form the polymer poly( 4- hydroxybutyrate ). When treated with a non - nucleophilic base, such as lithium diisopropylamide, GBL undergoes deprotonation alpha to the carbonyl. The related compound caprolactone can be used to make a polyester in this manner.
 

Polymerization
A variety of catalysts promote the ring-opening polymerization of butyrolactone, poly ( GBL ). The resulting polybutyrolactone reverts to the monomer by thermal cracking. It is claimed that poly ( GBL ) is competitive with commercial biomaterial poly( 4- hydroxybutyrate ), or P4HB. It is further claimed that poly ( GBL) is cheaper to make than P4HB, although both are bio - derived.
