Thiourea, an organic compound with the formula (NH2)2CS, has a wide range of applications across various industries. In the chemical industry, it is commonly used as a reducing agent in processes such as the reduction of peroxides to diols and the reductive workup of ozonolysis to produce carbonyl compounds. It is also used to convert alkyl halides to thiols, which is advantageous because it avoids the formation of dialkyl sulfides, a common side product when using other reagents.
In the textile industry, thiourea is utilized as a reducing agent for vat dyes, which are used to color fabrics. In photography,it serves as a fixing agent to remove unexposed silver halide from photographic emulsions. Additionally, thiourea is used in the production of synthetic resins and as an accelerator in the vulcanization of rubber, enhancing the mechanical properties of the rubber products.
In the agricultural sector, thiourea is added to fertilizers to improve their nitrogen content, thereby enhancing crop yields.However, its use in fertilizers can also contribute to water pollution, so its concentration needs to be carefully monitored.
Overall, thiourea's versatility and wide range of applications make it an important compound in both industrial and scientific contexts.
