Methyl Thioglycolate
Methyl Thioglycolate (CAS: 2365-48-2) is the methyl ester of thioglycolic acid, supplied as a colorless, oily liquid with a characteristic sulfur odor. It is a key intermediate for organotin heat stabilizers used in PVC processing, and a building block for pharmaceuticals, agrochemicals, and hair-care actives derived from thioglycolic acid. The thiol and ester functions in one molecule support diverse derivatization, including transesterification and thioether formation. The liquid has a characteristic sulfur odor and is handled in closed systems with odor control. Customers select it where a mercapto ester intermediate with reliable reactivity is required.
• PVC stabilizers: a key raw material for organotin mercaptide heat stabilizers used in rigid PVC.
• Cosmetics: a building block for thioglycolic acid derivatives used in perming and depilatory products.
• Synthesis: thiol plus ester groups support thioether, transesterification, and amide chemistry.
• Handling: moisture-sensitive, odorous liquid stored under controlled conditions.
