Used as a sulfurizing agent in the synthesis of organosulfur compounds, particularly in the preparation of sulfides and disulfides. It serves as a key reagent in pharmaceutical and agrochemical industries where sulfur-containing moieties are essential for biological activity. Also applied in polymer chemistry to introduce disulfide linkages, enhancing material stability and enabling responsive behavior under redox conditions. Its role in heterocyclic synthesis supports the development of functional materials and bioactive molecules.
