Identification
Name:Thioglycolate
DescriptionThioglycolic acid (TGA) is the organic compound HSCH2CO2H. It contains both a thiol (mercaptan) and a carboxylic acid. It is a clear liquid with a strong unpleasant odor. It is readily oxidized by air to the corresponding disulfide [SCH2CO2H]2. It is use during the conversion of chloro-alanine to S-carboxymethyl-L-cysteine.
