Synonyms: Mercaptoacetic acid
Formula: HSCH2COOH
Formula Weight: 92.12
CAS No.: 68-11-1
Density: 1.25 g/mL at 25 °C(lit.)
Storage Temperature: 2-8°C
Caution: At room temperature, concentrations over about 70% in water tend to form 1-2% thioglycolides per month which hydrolyze to the original free compound when made acid or alkaline. The 70% solution oxidizes in air but is stable at room temperature when tightly closed. Thioglycolate salts may also lose purity on storage. The exclusion of air does not materially improve stability.
