This benzimidazole derivative is an important fine chemical intermediate widely used in pharmaceutical and agrochemical industries. It possesses active mercapto and chlorine groups to participate in substitution, condensation and cyclization reactions for constructing complex heterocyclic structures. It is mainly applied to synthesize antibacterial, anti-inflammatory and antiparasitic medicines, effectively improving drug bioavailability and curative effect. It also acts as key raw material for high-efficiency fungicides and insecticides to prevent crop diseases and pests. Besides, it can be used to prepare corrosion inhibitors, dye intermediates and analytical chemical reagents. Its stable molecular framework and excellent reactivity make it widely applied in new drug research, pesticide production and functional material synthesis.

This chemical features moderate toxicity and obvious irritation hazards. Inhalation of floating powder will stimulate respiratory tract and cause cough and throat soreness, conduct all operations in well-ventilated area with dust-proof mask. Direct skin contact easily causes red swelling, itching and allergic inflammation, wear protective gloves and clean contaminated skin immediately. Eye contact leads to sharp stinging and conjunctival injury, flush eyes with running water continuously for more than fifteen minutes. Accidental intake will damage digestive system and internal organs. Thermal decomposition generates toxic chloride and sulfur-containing fumes. Keep far away from fire source, high temperature and oxidizing substances. Never store together with food and daily articles. All waste shall be disposed as hazardous waste to eliminate personal injury risk and environmental pollution.
