433-53-4, also known as gamma-Butyrolactone (GBL), is an industrial chemical used for a variety of purposes in the chemical and manufacturing industries. It is a colorless, water-soluble liquid, with a faint odor and sweet taste.

GBL is an important intermediate in the production of many industrial chemicals. It is primarily used as a starting material in the manufacture of 1,4-butanediol (BDO), a versatile chemical with numerous industrial applications, including plastics production, pharmaceuticals, and coatings among other applications. It can also be used in the production of pyrrolidines and gamma-aminobutyric acid (GABA) derivatives.

Furthermore, GBL has been used as a solvent in the production of brake fluids, explosives, pesticides, dyes, adhesives and pesticides. Furthermore, GBL has also been employed as a fuel additive in particular formulations in order to improve combustion and reduce emissions.

GBL is also known to be a common source of the recreational drug GHB, or gamma-hydroxybutyric acid, also referred to as liquid ecstasy or simply, G. GHB is a Schedule I controlled substance in the United States and its criminal sale and possession are strictly prohibited and heavily sought after by law enforcement agencies. GBL is a metabolite of GHB, and as a result, GBL can cause the same adverse health effects that are associated with GHB, including euphoria, lowered inhibitions, confusion, dizziness, and nauseousness.

Overall, 433-53-4 is a versatile industrial chemical with an important range of applications. Due to its relatively low cost and relative ease of access, GBL is a widely used chemical in the manufacturing industry, and can be found in a variety of products and processes.
