Detailed Product Description:
Thiourea is an organic compound of carbon, nitrogen, sulfur and hydrogen.
It is similar to urea, except that the oxygen atom is replaced by a sulfur atom.
The properties of urea and thiourea differ significantly because of the relative
electronegativities of sulfur and oxygen. Thiourea is a versatile reagent in
This is Reagent grade material with a minimum purity of 99%.
A currently common application for use of thiourea is as a sulfur source for
making semiconductor cadmium sulfide nanoparticles. A slurry of 1 g cadmium
sulfate, 0.5 g thiourea, and 0.1 g SiO2) were sonicated for 3 hours under ambient
air at room temperature. The colorless slurry solution changes to yellow
indicating the generation of CdS.
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.
Thiourea is considered a possible human carcinogen and mutagen according to
Directive 67/548/EEC. A goitrogenic effect (enlargement of the thyroid gland) has
been reported, and hepatic tumors have resulted from chronic administration in rat.
Bone marrow depression also has been reported.
May cause irritation to skin, eyes, and respiratory tract. Combustible.
