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 manufacturing of resins and polymers, where it acts as a curing agent or accelerator in rubber vulcanization. In photography, thiourea is employed in toning solutions to enhance image stability and contrast. It is also utilized in electroplating processes, especially in silver and gold plating, due to its ability to stabilize metal ions in solution. In analytical chemistry, thiourea serves as a masking agent for metal ions during titrations and colorimetric analyses. Additionally, it finds application in textile and dye industries as a bleaching agent and in the production of flame-retardant materials.
