Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block in the formation of sulfur-containing compounds due to its disulfide linkage, which can participate in redox reactions. Employed in the development of certain biologically active molecules, including antimicrobial and antifungal agents. Also utilized in research settings for modifying peptides and proteins through disulfide bond formation. Its reactivity makes it valuable in the synthesis of specialty chemicals and in polymer chemistry as a crosslinking agent.
