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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
