Used primarily in organic synthesis, it serves as a key reagent for introducing thiol groups into molecules. It is also employed in the preparation of metal complexes and ligands, particularly in coordination chemistry. Its ability to form stable bonds with metals makes it useful in creating catalysts for various chemical reactions. Additionally, it finds application in the production of polymers and resins, where it acts as a cross-linking agent to enhance material properties. It is utilized as an intermediate in the synthesis of pesticides and agricultural chemicals, as well as in the production of sulfur-containing compounds in the petrochemical industry. In some cases, it is utilized in surface modification processes, including metal surfaces, to improve adhesion or corrosion resistance. Its role in biochemical research includes acting as a reducing agent for disulfide bonds in proteins, aiding in structural studies. Furthermore, it is used in laboratory research to study chemical reactions involving sulfur compounds.
