APPLICATIONS
1,2,3-Benzotriazole: Benzene ring-fused azole compounds; white to off-white crystalline powder; insoluble in water, soluble in ethanol, melting at 98.5 C. Azole is a five-membered heterocycle compound containing unsaturated bonds and Nitrogen atoms. Triazole has three nitrogens. 1,2,3-Benzotriazole (1H-benzotriazole) has -N=N- bond whereas 2H-Benzotriazole has two -C=N- bonds. Benzotriazole is a parent material to produce UV-absorbers. Benzotriazole and its derivatives are versatile intermediates involved in the production of:
  • Corrosion Inhibitors
  • Anti-fading agent for metals
  • Antiseptic and Anticoagulant agent
  • Anti-fog for photograph
  • UV-absorbers
  • Anti-freeze Agent
  • Photoconductor
  • Copying systems
  • Pharmaceuticals, pesticide products and other specialty chemicals
