Used as a stabilizing agent in the production of polymers, particularly in the synthesis of polyvinyl chloride (PVC), to control molecular weight and improve thermal stability. It serves as a key intermediate in the manufacture of pharmaceuticals, including drugs for treating hypertension and cardiovascular diseases. In the agricultural sector, it is employed in the synthesis of pesticides and herbicides, enhancing their effectiveness. Additionally, it is utilized in the preparation of self-assembled monolayers (SAMs) for surface modification in nanotechnology applications. Its thiol group makes it valuable in biochemical research for protein labeling and cross-linking studies.
