1Liter GBL / Gamma Butyrolactone CAS: 96-48-0

GBL γ-Butyrolactone (GBL) is a hygroscopic colorless liquid with a weak characteristic odor. Soluble in water, GBL is a commonsolvent and reagent in chemistry as well as being used as a flavouring, as a cleaning solvent, as a superglue remover, and as asolvent in some wet aluminium electrolytic capacitors. In humans it acts as a prodrug for γ-hydroxybutyric acid (GHB), and it is used as a recreational intoxicant with effects similar to alcohol.

GBL Description

1. 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.

2. 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.

3. Gamma-Butyrolactone ( γ – butyrolactone or GBL ) is a hygroscopic colorless liquid with a weak characteristic odor which is soluble in water.

4. GBL is a common solvent and reagent in chemistry as well as being used as a flavouring, as a cleaning solvent, as a superglue remover, and as a solvent in some wet aluminium electrolytic capacitors. In humans it acts as a prodrug for GHB, and it is used as a recreational intoxicant with effects similar to alcohol.

 

Applications

Nutritional supplement:

Recreational drug:

(1). GBL can be used to produce a-pyrrolidone, 1 – Methyl -2- pyrrolidinone , polyvinyl pyrrolidone, and α – Acetyl – γ – butyrolactone, etc.

(2). GBL can be used as anaesthetic and tranquilizer, used to produce ciprofloxacin and interferon, as the intermediate of vitamin and rolicyprine;

(3). GBL is the intermediate of plant growth stimulator and insecticide.

(4). GBL is a good antioxidant, plasticizer, extractant, adsorbent, dispersant, fixative and curing agent; Moreover, it can also be used in battery, capacitor and development of color film.
