Applications
Reagent that protects tryptophan in amino acid analysis.Mercaptoacetic acid is used as a protecting agent for tryptophan in amino acid analysis and an acidity indicator. It finds application as an intermediate in the chemical reactions such as addition, elimination and cyclization. It acts as a precursor to ammonium thioglycolate, sodium thioglycolate and calcium thioglycolate. Its organotin derivatives are used as stabilizers for polyvinyl chloride (PVC). In organic synthesis, it acts as a nucleophile in thioglycolysis reactions and sulfur transfer agent for sulfonyl chloride synthesis. Further, it is used in leather processing.

Solubility
Miscible with water, ethanol, ethers, ketones, esters, chlorinated hydrocarbons, benzene and aromatic hydrocarbons. Slightly miscible with chloroform.

Notes
Air sensitive. Incompatible with strong oxidizing agents and strong acids.
