Description

Sodiumdimethyldithiocarbamate40% CAS NO 128-64-1 is a high-purity aqueous solution of the sodium salt of dimethyldithiocarbamic acid, a versatile organosulfur compound. This product serves as a critical intermediate and active ingredient valued for its metal-chelating and biocidal properties. It is essential for manufacturers in the water treatment, rubber processing, and agricultural chemical industries seeking reliable, consistent-quality raw materials for their formulations.

Application

• Water Treatment: Acts as a highly effective biocide and slimicide in industrial cooling water systems, paper mills, and oilfield water to control microbial growth.
• Rubber Industry: Used as an ultra-accelerator in the vulcanization process of synthetic rubbers, improving cure rates and physical properties.
• Agricultural Chemicals: Serves as a key precursor in the synthesis of certain fungicides and pesticides, including metam sodium.
• Metal Chelation & Precipitation: Employed in analytical chemistry and wastewater treatment to chelate and remove heavy metal ions like copper, nickel, and cadmium.
• Polymerization: Functions as a short-stop agent to terminate free-radical polymerization reactions in the production of synthetic latex and resins.
• Fungicide for Wood & Textiles: Provides protective treatment against fungal decay for wood products and certain textiles.
