  • Applications

    Zinc thiosalicylate (CAS 16742-82-8) is primarily used as a chelating/complexing agent in industrial formulations, helping bind metal ions and stabilize systems such as coatings, inks, and cleaners. It may function as a processing aid or stabilizer in certain polymers and plastics, contributing to metal ion control and color stability during manufacturing. In analytical and research settings, it serves as a ligand in coordination chemistry and as a reagent for metal ion detection or separation. It can also act as an intermediate or precursor in organic synthesis for the preparation of metal–salicylate complexes and related compounds. Applications are formulation-dependent and subject to local regulations and formulation limits.
