Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its structure allows for the introduction of trifluoromethylthio and chloromethyl functional groups into larger molecules, enhancing lipophilicity and metabolic stability in drug candidates. Commonly employed in the development of bioactive compounds where the trifluoromethylthio group improves membrane permeability and biological activity. Also utilized in the preparation of sulfane-based ligands and functional materials in organic chemistry research.
