Used as a curing agent and crosslinking promoter in rubber and polymer industries, particularly in the production of high-performance tires and industrial rubber goods. Its structure enables efficient sulfur-based crosslinking, improving heat resistance, tensile strength, and durability of vulcanized rubber. Also employed in specialty adhesives and sealants where enhanced thermal and mechanical stability are required. Shows utility in synthesizing chelating agents and ligands for metal ion recovery and catalysis due to its dual amine and thiol functionality. Additionally, it serves as a leucine aminopeptidase inhibitor in biochemical and enzymatic research applications.
