Product Name:Thiourea dioxide
English Name:Thiourea dioxide
CAS No.:1758-73-2
Aliases:Formamidine sulfinic acid, Aminoiminomethanesulfinic acid
Molecular Formula:CH4N2O2S
Physical Properties:White, odorless crystalline powder; stable in air, neither oxidizing nor reducing. Molecular weight 108.12. Melting point 124-127 °C (dec.), boiling point 355.3±25.0 °C (predicted), density 1.68 g/cm³, refractive index 1.6550 (estimated). Solubility in water about 30 g/L at 20 °C; pH of 10 g/L aqueous solution about 4 at 20 °C. Storage condition 2-8 °C.
Uses:As a strong reducing agent, it is widely used in chemical, textile and dyeing industries for wool bleaching, vat dye and sulfur dye dyeing, reduction cleaning after disperse dye dyeing, and discharge decolorization. It is also used as a synthetic fiber auxiliary, decolorizing agent, photographic emulsion sensitizer, chloroprene polymerization agent, and separating agent for rhodium and iridium. It can reduce ketones to secondary alcohols and is used as a PVC stabilizer.
