Thiourea Dioxide (TDO or TUD) is also named as Formamidine Sulfinic Acid. Its appearance is white crystal powder. Thiourea Dioxide is a stable compound with no strong reducing and oxidizing ability, and its dissolvability is 26.7g/l (20 oC), while its PH is 5.0 in saturated solution. Thiourea Dioxide (TDO) appears terrific stable even in 20oC -30oC solution, but when it is under heat or catalysesing by alkali, it decomposes gradually to produce sulfoxylic acid through formamidine sulfinic acid to exhibit a reducing action.

Thiourea Dioxide (TDO) is a new kind of reducing agent that used as exchange of sodium hydrosulfite. It is widely used in textile and paper making industry. This product is also used in leather processing industry, paper, pulp and board industry, photographic industry, bleaching and reducing agents. This product is also a component of decolorisation agents. In macromolecule material industry, it is used as catalysis agent and stabilizer of resinic producing, and it is also used in organic synthesization of sensitizing material, and medicine, medical, spicery materials in fine chemicals, and also can be applied in the recycling and separating of heavy metals.
