  Detailed Description: Cas No. :1758-73-2

Product Name: Formamidinesulfinic acid
CAS RN.: 1758-73-2
Molecular Formula: CH4N2O2S

Properties:
Appearance: white odorless crystalline powder
M.P.: 126oC
Solubility: 26.7g/1L water

Use: Widely used in chemical engineering, textiles industries;as strong reducing agent, it has gradually taken the place of rongalite in printing & dyeing area. 

Thiourea dioxide is white crystalline powder, solubility in water is 26.7g/L(20oC), pH value of saturated aqueous solution is 5.0; its aqueous solution is very stable at 20-30oC; but will have very high reduction potential(-1230Mv)when heated. 

Thiourea dioxide is a new-type, environmentally friendly products used as substitute of rongalite. It has very high reduction potential, is non-toxic, very stable, non-toxic, tasteless and environmentally friendly. It has been widely used in the dyeing of vat dyes and sulfur dyes, bleaching of wool and real silk, cleaning of disperse dyes, cleaning of dye vat etc. It is also used as reducing agent, bleaching agent, plastic stabilizer, anti-oxidants for organic synthesis, and sensibilizer of sensitive materials.
