Application:	Thioglycolic acid may be used as a sulfur source for the synthesis of metal sulfide nanostructures via hydrothermal process.
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.
General description:	Thioglycolic acid is a mercaptocarboxylic acid that serves as a stabilizer, reducing agent, and ligand.
Packaging:	100, 500 mL in glass bottle
