Product Description:

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

GBL has been found in extracts from samples of unadulterated wines.[3] This finding indicates that GBL is a naturally occurring component in some wines and may be present in similar products. The concentration detected was approximately 5 μg/mL and was easily observed using a simple extraction technique followed by GC/MS analysis.

GBL can be found in cheese flavourings but typically results in a content of 0.0002% GBL in the final foodstuff.

Application:

1)it is Used to produce a-pyrrolidone, 1-Methyl-2-pyrrolidinone, polyvinyl pyrrolidone, and α -Acetyl-γ -butyrolactone; 2) it is used as anaesthetic and tranquilizer, used to produce ciprofloxacin and interferon, as the intermediate of vitamin and rolicyprine; 3) As antioxidant, plasticizer, extractant, adsorbent, dispersant, fixative and curing agent; 4) it is Used in battery, capacitor and development of color film.
