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.
2-(2'-Hydroxy-5'-t-octytphenyl)benzotriazole is
a UV absorber for polymers |
