Used as an accelerator in the vulcanization of rubber, particularly in the production of sulfur-vulcanized rubber products. It enhances the cross-linking process, improving the elasticity, strength, and durability of rubber materials. Commonly applied in manufacturing tires, hoses, belts, and other rubber goods requiring high performance and thermal stability. Also serves as an intermediate in the synthesis of certain pharmaceuticals and corrosion inhibitors due to its sulfur-containing structure.
