Thiourea Formula: Structure, Sample, Properties and Uses

The Thiourea Formula is composed of Carbon, Hydrogen, Nitrogen, and Sulphur. Carbon, denoted by the letter C in the periodic table and belonging to group 14, is the most abundant non-metallic element. It is responsible for a wide range of chemical compounds. Hydrogen, also a non-metallic element, is the first on the periodic chart without any discernible properties such as smell, color or taste. Represented by H, it exists in a gaseous state. Another frequent member of group 15 is nitrogen, symbolized by N and known to be the lightest in its family. Finally, sulphur takes its place in group 16 with the highest level of reactivity and can be identified by the letter S.

Thiourea Formula Structure

Compared to urea, thiourea is an organosulphur chemical whose oxygen atoms have been replaced with sulfur atoms. There are other names for thiourea, including pseudothiourea and thiocarbamide. Its chemical formula is CH ₄ N ₂ S. When it comes into contact with fire, it emits hazardous gases. It is important for the formation of heterocycles.

The organic molecule thiourea (also known as thiocarbamide) is composed of carbon, nitrogen, hydrogen, and sulfur atoms in its chemical formula SC(NH ₂ ) ₂ - a similar composition to urea. However, instead of oxygen, the sulfur atom replaces the oxygen atom in thiourea. It is important to note that while these two compounds share a structural resemblance, they possess different physical and chemical properties. Thiourea is typically produced by heating ammonium thiocyanate (NH ₄ SCN) or adding hydrogen sulfide to cyanamide. Although it has some similarities to urea, thiourea is not as widely used. In fact, it is mainly utilized in photography as a fixing agent and also finds applications in the production of thermosetting resin, as an insecticide, textile treatment, and as a starting material for colors and pharmaceuticals. At 182° C (360° F), thiourea crystallizes into colorless crystals and can be toxic if consumed; however, the lethal dose has not been determined yet.
