Diphenylthiourea is a widely used sulfur-containing organic intermediate and chemical auxiliary agent. It has stable molecular structure and strong complexing ability, which can participate in condensation, addition and cyclization reactions to synthesize various fine chemical products. It is mainly applied as vulcanization accelerator and antioxidant in rubber industry to improve rubber elasticity and aging resistance. It also acts as effective metal flotation agent for mineral separation in mining industry. In pharmaceutical field, it is used for preparing bacteriostatic agents and medical synthetic intermediates. Besides, it serves as chemical analytical reagent, corrosion inhibitor and dye synthesis raw material, and plays an important role in daily chemical industry, electroplating industry and organic synthesis research.

This chemical has moderate toxicity and obvious irritant effect on human tissues. Inhalation of fine dust will stimulate respiratory mucosa, cause dry throat, cough, chest tightness and other discomforts, and long-term inhalation may affect respiratory function. Skin contact easily causes local redness, itching and allergic dermatitis, repeated contact will damage skin surface protective layer. Eye contact will lead to severe stinging, tearing and conjunctival inflammation, timely long-time water flushing is required after contact. Accidental ingestion will cause nausea, vomiting, abdominal pain and other gastrointestinal poisoning symptoms. Operators must work in well-ventilated environment, wear dust-proof masks, chemical resistant gloves and safety goggles. Keep products away from food and daily necessities during storage. Waste materials and leftover materials shall be treated in accordance with hazardous waste disposal norms to prevent soil and water pollution and avoid unnecessary health hazards.
