Urea and Thiourea Differences
The difference between urea and thiourea
Urea and thiourea, both are chemical substances, but their properties and uses are different.
Urea, carbamide is also, its molecular formula is $CO (NH_2) _2 $. The appearance is often white crystalline, easily soluble in water, and has applications in many fields. In agriculture, urea is a commonly used nitrogen fertilizer, which can supply nitrogen for plant growth, promote the flourishing of stems and leaves, but apply too much, or cause soil compaction and water eutrophication. In industry, it is also used to make plastics, medicines, etc. Because of its high nitrogen content, it is an important raw material in organic synthesis.
As for thiourea, the molecular formula is $CS (NH_2) _2 $, and the appearance is mostly white crystal, but its solubility is slightly different from that of urea, and its solubility in water is slightly inferior. The chemical properties of thiourea are more active and reductive than urea, and it is often used as an inhibitor of metal mineral flotation. It can be used as a brightener in the electroplating industry to improve the quality of the coating. In medicine, there are also studies related to its medicinal potential, such as anti-tumor exploration.
Looking at the structure of the two, urea is connected with an amino group by a carbonyl group, while thiourea replaces the carbonyl group of urea with a thiocarbonyl group. This structural difference makes its properties different. The chemical properties of urea are relatively stable, while thiourea is more prone to nucleophilic reactions due to the presence of sulfur atoms. In terms of physical properties, the melting point, boiling point, etc. are also different. The melting point of urea is about 132.7 ° C, and the melting point of thiourea is about 182-186 ° C.
To sum up, although urea and thiourea have similar appearance, due to different structures, there are significant differences in properties and uses, and they play unique roles in various fields.
