Glycol dimercaptoacetate Usage And Synthesis

Chemical Properties

clear liquid

Uses

Crosslinking agent for rubbers, accelerator in curing epoxy resins. This ester has little more than academic interest, but it may be formed in small quantities in cosmetic preparations when Thioglycolic acid and Ethylene glycol are used at the same time.

Synthesis Reference(s)

Tetrahedron Letters, 27, p. 3791, 1986 DOI: 10.1016/S0040-4039(00)83882-4

Synthesis

Glycol dimercaptoacetate is produced by estenfication of Ethylene glycol with Thioglycolic acid.
