Application

Thioglycolic acid may be used as a sulfur source for the synthesis of metal sulfide nanostructures via hydrothermal process.

Packaging

100, 500 mL in glass bottle

Caution

At room temperature, concentrations over approximately 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.
