Thiourea exhibits many of the chemical properties of urea, but it has little commercial application. "Thioureas" refers to a broad class of compounds with the general structure (R R N)(R R N)C=S. Like urea, it can be prepared by causing a compound with the same chemical composition to undergo rearrangement, as by heating ammonium thiocyanate (NH4SCN). Corrections? It dissolves in water, ethanol, and ammonium thiocyanate solution. It is an organosulfur compound and its structure is similar to urea, except that the sulfur atom replaces the oxygen atom. CopyCopied, InChI=1S/CH4N2S/c2-1(3)4/h(H4,2,3,4) The properties of urea and thiourea differ significantly. Thioureas are related to thioamides, e.g. Thiourea is a reagent in organic synthesis. Like urea, it can be prepared by causing a compound with the same chemical composition to undergo rearrangement, as by heating ammonium thiocyanate (NH 4 SCN).

Thiourea, also called thiocarbamide, an organic compound that resembles urea (q.v.) Incompatible with strong acids, strong bases, strongoxidizing agents, metallic salts, proteins, hydrocarbons. A method of preparation more commonly used consists of the addition of hydrogen sulfide to cyanamide. Thiourea, also called thiocarbamide, an organic compound that resembles urea (q.v.) The small quantity of thiourea consumed is utilized primarily in photography as a fixing agent, in the manufacture of a thermosetting resin, as an insecticide, as a textile-treating agent, and as starting material for certain dyes and drugs. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... …halogen) with the sulfur reagent thiourea, (NH, …of an organic compound (thiourea) to the iron chloride etching bath.
