Thiourea is widely used in the synthesis of pharmaceuticals, particularly as an intermediate in the production of antithyroid drugs and certain antibiotics. It plays a key role in the manufacture of resins and polymers, especially in improving the curing process of chloroprene and other synthetic rubbers. In the textile industry, thiourea derivatives are applied in flame-retardant finishes and as dyeing assistants to improve fabric quality. It is also employed in electroplating processes, where it acts as a catalyst for nickel, copper, silver, and gold plating, helping in the deposition of smooth, uniform, and durable metal coatings. In photography, thiourea is used in toning and fixing solutions to enhance image stability. Additionally, it serves as a reducing agent and stabilizer in various chemical reactions and industrial formulations. In the paper industry, it controls chlorine formation during bleaching processes. It is an intermediate in the production of fungicides and certain pesticides. In laboratory analysis, thiourea is used for detecting heavy metals such as mercury and lead. In the rubber industry, it accelerates sulfur vulcanization.
