Application:
Thiourea can reduce peroxides to the corresponding diols.Thiourea is also used in the reductive workup of ozonolysis to give carbonyl compounds.Thiourea is commonly employed to convert alkyl halides to thiols.Thioureas are used a building blocks to pyrimidine derivatives. Another common application for use of thiourea is a common sulfur source for making semiconductor cadmium sulfide nanoparticle.Other industrial uses of thiourea include production of flame retardant resins, and vulcanization accelerators. Thiourea is used as an auxiliary agent in diazo paper (light-sensitive photocopy paper) and almost all other types of copy paper. The liquid silver cleaning product TarnX is essentially a solution of thiourea. A leaching agent for gold leaching and silver leaching can be created by selectively oxidizing thiourea, bypassing the steps of cyanide use and smelting.
