THIO UREA - CHINA

Production and Reactions
General Information

It is an organosulfide compound that resembles urea, which is formed by the substitution of the Sulfur atom instead of the Oxygen atom of urea, whose chemical formula is CH4N2S. Sulfocarbamide is also known as sulphourea or thiocarbamide. It is a toxic substance. It is a reagent in organic synthesis. It is structurally similar to urea, but the properties of urea and thiourea are significantly different.

It can be prepared by treating the appropriate cyanamide with "LiAlHSH" in the presence of 1 N HCl in anhydrous diethyl ether. "LiAlHSH" can be prepared by treating lithium aluminum hydride with elemental sulfur. It can be prepared by combining two amines with thiophosgene.
Like thioamides, thiourea can serve as a sulfide source upon reaction with soft metal ions. Mercury salts in aqueous solution can be treated with thiourea.
