Function:
Pure thioglycolic acid is a colorless transparent liquid, while industrial products are colorless to slightly yellow with a strong pungent odor. It is miscible with water, ethanol and ether.
Application:
Thioglycolic acid (TGA) is mainly used as a raw material for blanket finishing agents and perm solutions. TGA has both the reaction characteristics of hydroxy acids and thiol groups, and the most important reaction is the reaction with disulfides.
Thioglycolic acid is an intermediate for the production of pharmaceuticals such as thiomethoprol (captolide), biotin, thiozinic acid, and sodium disulfide succinate. It is also an important raw material for the synthesis of cysteine, hormone agents, industrial disinfectants, and synthetic sulfuric acid.
In addition to being used as an intermediate for Cefivitril, thioglycolic acid is also widely used as a curling agent, depilatory agent, PVC low-toxic or non-toxic stabilizer, metal surface treatment agent, and polymerization reaction initiator, accelerator, and chain transfer agent.
It is a sensitive reagent for iron, molybdenum, silver, and tin. Its ammonium salt and sodium salt are used as curling and perm agents, and its calcium salt is a depilatory agent.
