The substance corresponding to CAS 68-11-1 is mercaptoacetic acid, also known as thioglycolic acid, which is an organic acid containing both thiol and carboxyl groups.

Basic physical and chemical properties

The molecular formula is C ₂ H ₄ O ₂ S, with a molecular weight of approximately 92.12. It appears as a colorless transparent liquid (industrial products may be slightly yellow) and has a strong unpleasant thiol odor. It is miscible with various solvents such as water, ethanol, and ether.

 
Main purpose
Its sodium and ammonium salts are the core raw materials of cold perm essence, and calcium salts can be used as hair removal agents; It can also be used as a sensitive reagent for detecting metals such as iron, molybdenum, and silver, and as an intermediate and chain transfer agent in organic synthesis.

 
Key points for safety and storage
This substance belongs to highly toxic and highly corrosive substances, which can cause strong irritation to the skin and eyes. It will burn and release highly toxic hydrogen sulfide gas when exposed to open flames. It needs to be sealed and stored in a cool and ventilated environment at 2-8 ℃, away from oxidants.
