Mail: buygblonline@gmail . c o m Website: www. buygblonline. o rg GBL is a thin liquid which is oily, has a weak odor, and is water soluble. It is actually a fairly common reagent in chemistry, and a common solvent. It can also be used as a stain remover, an aroma compound, a paint stripper, a superglue remover and as a solvent in some electrical capacitors, chiefly aluminum electrolytic capacitors. GBL goes by different names, including GBL, butyrolactone, 1.4-lactone, 4-butyrolactone, 4-hydroxybutyric acid lactone, and also gamma-hydroxybutyric acid lactone. Its CAS number is 96-48-0 and its RTECS number is LU3500000. It can be found in samples of wines that are unadulterated, and it believed that this is how it is produced naturally. It can be synthesized from gamma-hydroxybutyric acid by removal of any water, or even by distillation. It can also be synthesized through the oxidation of tetrahydrofuran.
