Product Description

Thiourea Dioxide

Thiourea dioxide (TDO), also known as formamidinesulfinic acid (FAS) or thiox, is an organosulfur compound with the chemical formula CH4N2O2S. It is a stable, white crystalline powder that functions primarily as a powerful reducing agent. In aqueous solution, TDO rapidly tautomerizes to its active form, formamidinesulfinic acid , which decomposes stepwise to sulfoxylic acid and urea, delivering the reducing power. 

It is widely used Textiles, Pulp & Paper, Leather Processing, Organic & Fine Chemical Synthesis, Polymer Industry, etc.
