Description and Uses

Thiosalicylic acid acts as a trapping agent, which is useful in the desulfenylation of 3-indolyl sulfides. It is used to prepare macrocyclic diamides by condensation with diamines. Further, it is used as a precursor to drug, which finds application for the treatment of atherosclerosis and melanoma. In addition to this, it is involved in the preparation of vaccine preservative thiomersal and thioindigo dyestuff.
