Used as an accelerator in the vulcanization of rubber, particularly in sulfur-based curing systems. It enhances the cross-linking process, improving the elasticity, strength, and durability of rubber products. Commonly applied in the manufacturing of tires, hoses, belts, and other technical rubber goods. Also serves as an intermediate in organic synthesis for sulfur-containing compounds. Its derivatives have shown activity in some antimicrobial applications, though industrial use remains focused on polymer modification.
