Chemical name: Formamidine sulfinic acid
Synonyms: Aminoiminomethanesulfinic acid; Thiourea dioxide
CAS No.: 1758-73-2
Molecular formula: CH4N2SO2
Molecular weight: 108.12
Properties:
White and smelless powder,a kind of stable product without oxidisability and reducing property. Solubility in water:26.7g/l(20℃) and PH value of saturated aqueous solution:5.0. It will be quite stable even if in 20-30℃ solution,but it would decompose in case of heat or alkali and give off sulphonic acid.
Usage:
Mainly used in dyeing industry as a substation of sodium hydrosulphite and used in organic synthesis,also used as additive of polymerization, stabilizer for polythene sensitizer of photographical emulsion and so on.
