Description

Dithiocarbamoyl Disulfide CAS NO 504-90-5 is an organosulfur compound belonging to the dithiocarbamate class, characterized by its disulfide linkage. This chemical serves as a versatile intermediate and functional additive, valued for its role in sulfur-based chemical synthesis and as a source of active sulfur. It is primarily sought after by manufacturers in the rubber and polymer industries, where it functions as a vulcanization accelerator and stabilizer, as well as by agrochemical producers for its utility in synthesizing specific fungicides and pesticides.

Application

• Rubber Vulcanization Accelerator: Acts as a secondary accelerator in the production of tires, hoses, belts, and other rubber goods, improving cross-linking efficiency and final product properties.
• Polymer Stabilizer: Used as an antioxidant or anti-aging agent in various polymer formulations to enhance thermal stability and longevity.
• Agrochemical Intermediate: A key building block in the synthesis of dithiocarbamate-based fungicides and pesticides.
• Lubricant Additive: Functions as an extreme pressure (EP) and anti-wear additive in industrial lubricants and greases.
• Metal Processing: Employed in ore flotation processes as a collector agent and in certain metal surface treatment formulations.
• Chemical Synthesis: Serves as a specialized reagent for introducing disulfide or dithiocarbamate functional groups in organic synthesis.
