Thiosemicarbazide is an essential sulfur-containing heterocyclic synthetic intermediate widely applied in multiple industrial fields. It actively participates in condensation and cyclization reactions to produce diversified thiazole, triazole and thiadiazole derivatives. In agrochemical industry, it serves as core raw material for manufacturing high-efficient fungicides, insecticides and plant growth regulators to protect crop growth. It is commonly adopted to synthesize antibacterial, anti-inflammatory and anti-tumor drugs in pharmaceutical research. Besides, it acts as sensitive analytical reagent for detecting metal ions and chemical components. It can also be used as polymerization inhibitor, rubber additive and corrosion inhibitor. Its active chemical structure enables abundant derivative reactions, occupying fundamental status in fine chemical, pesticide and medical synthesis.

This chemical carries moderate toxicity and obvious irritant hazards. Inhalation of floating powder will stimulate respiratory tract and trigger cough and chest discomfort, conduct operation under ventilation and wear protective mask. Direct skin contact easily causes red swelling, itching and allergic inflammation, wear anti-corrosion gloves and clean contaminated skin promptly. Eye contact leads to severe stinging pain and conjunctival injury, continuously flush eyes with running water for more than fifteen minutes. Accidental intake will damage digestive system and internal organs. Thermal decomposition generates toxic harmful gas. Keep far away from fire source, high temperature and strong oxidizing substances. Strictly separate storage from food supplies. All waste materials must be disposed as hazardous chemicals to eliminate personal injury risks and environmental pollution.
