Gamma-butyrolactone — also known by its product name "GBL" or CAS No. 96-48-0 — is a versatile cyclic ester used throughout many applications. Rather than seeing GBL on its own, most will employ GBL to produce derivative chemicals. GBL is also a popular solvent in several cosmetic products. The need for gamma-butyrolactone in industries throughout North America is significant.

Quick Answers

Gamma-butyrolactone is an ideal antioxidant, plasticizer, dispersing agent, and solvent. However, GBL is perhaps most commonly used as an intermediate in the production of derivative chemicals like methyl-2-pyrrolidone, also known as NMP. As well as its use in chemical production, GBL is known as a fragrance agent in some household products as well as a solvent in lotions, nail polish removers, and some polymers. You can also use it in battery and capacitor production when you mix it with a small amount of ethylene glycol.
