3-mercapto-1, 2-propylene glycol is an organic compound also known as mercaptopropylene glycol or mercapto glycerol.
Nature:
3-mercapto-1, 2-propylene glycol is a colorless to light yellow liquid. It has two hydroxyl groups and a sulfhydryl group (a functional group formed by combining a sulfur atom with a hydrogen atom), which gives this compound a certain hydrophilicity.
1. Used as stabilizer and polymerization regulator of acrylonitrile polymer; Modifier of reactive dyes; Sensitizer raw materials for photosensitive coatings; Epoxy resin coating polymerization adjuster; Catalyst of epoxy monoamine resin; Stabilizer of chlorine-containing polymer, etc.
2.3-mercapto-1, 2-propylene glycol is widely used in organic synthesis. It can be used to make thiamine (vitamin B1), mercaptoglycine (a common amino acid), and mercaptotyramine (an antioxidant). It can also be used as a rubber accelerator, antioxidant, flame retardant for metal materials and so on.
