Thiourea (/ ˌ θ aɪ. oʊ j ʊəˈr iː. ə,-ˈ jʊər i-/) [2] [3]}} is an organosulfur compound with the formula SC(NH 2) 2 and the structure H 2 N−C(=S)−NH 2. It is structurally similar to urea ( H 2 N−C(=O)−NH 2 ), with the oxygen atom replaced by sulfur atom (as implied by the thio- prefix).

Thiourea (thiocarbamide) has been used as a fixative in photography and photocopying. It has also been used as a rubber and neoprene antioxidant. Photocontact dermatitis caused by thiourea has been observed in users of shoe insoles, …

The parent member of this class of compounds is thiourea (S=C(NH 2) 2). Substituted thioureas are found in several commercial chemicals.

thiourea, an organic compound that resembles urea (q.v.) but contains sulfur instead of oxygen; i.e., the molecular formula is CS(NH 2) 2, while that of urea is CO(NH 2) 2. 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).

What is Thiourea? Thiourea is an organosulphur compound similar to urea in which the oxygen atom is replaced by a sulphur atom. Thiourea is the sulphur analogue of urea. Thiourea is used for its synthetic equivalence to hydrogen sulphide. It plays an important role in the construction of heterocycles. It appears as white crystals, which are ...

Thiourea, when used in conjunction with high concentrations of urea, has led to significant improvements in the recovery of proteins from the nucleus, integral membranes, and tubulin compared to classical solubilization solutions as demonstrated by two-dimensional electrophoresis (2DE) (Rabilloud, Adessi, Giraudel, & Lunardi, 1997).

THIOUREA is a carcinogenic, deadly white crystalline substance or powder. When heated to breakdown, it emits extremely dangerous sulphur and nitrogen oxide vapors. As a result, thiourea elimination by chemical oxidation and/or chemical adsorption is critical in …

Based on these significant discoveries of thiourea, thiourea derivatives have attracted increasing attention in medicinal chemistry and drug discovery. Importantly, thiourea is a well-known urease inhibitor, which could be used as a positive control and lead compound for the investigation of novel urease inhibitors ( Fig. 1 ) [ 36 ].

Thiourea occurs in two tautomeric forms: Synthesis of thiourea. The global annual production of thiourea is around 10,000 tons. About 40% is produced in Germany, another 40% in China, and 20% in Japan.
