WebMercaptoacetic acid (thioglycolic acid) 98%. Mercaptoacetic acid (Thioglycolic acid) Formula: HSCH₂COOH MW: 92.12 g/mol Boiling Pt: 220 °C (760 mmHg) Melting Pt: –16 °C … Thioglycolic acid (TGA) is the organic compound HSCH2CO2H. TGA is often called mercaptoacetic acid (MAA). It contains both a thiol (mercaptan) and carboxylic acid functional groups. It is a colorless liquid with a strongly unpleasant odor. TGA is miscible with polar organic solvents. See more TGA is used as a chemical depilatory and is still used as such, especially in salt forms, including calcium thioglycolate and sodium thioglycolate. TGA is the precursor to ammonium thioglycolate, which is used for See more Thioglycolic acid is prepared by reaction of sodium or potassium chloracetate with alkali metal hydrosulfide in aqueous medium. It can be also prepared via the Bunte salt obtained … See more The LD50 (oral, rat) is 261 mg/kg, LC50 inhalation for rat is 21 mg/m for 4 h, and LD50 dermal for rabbit is 848 mg/kg.
