Trithiocyanuric acid is primarily used in the synthesis of organic compounds, particularly in the production of rubber vulcanization accelerators. It enhances the cross-linking of polymer chains, improving the elasticity, durability, and heat resistance of rubber products. Additionally, it serves as a precursor in the manufacture of herbicides and pesticides, where its chemical properties help in controlling weed and pest growth. In the field of material science, it is utilized for modifying surfaces to improve adhesion and corrosion resistance. Its applications also extend to water treatment processes, where it aids in the removal of heavy metals due to its strong chelating properties.
