What is 5-Chlorobenzotriazole ?

Chemical properties

OFF-WHITE POWDER

The Uses of 5-Chlorobenzotriazole

5-Chlorobenzotriazole is a good inhibitor; it decreases anodic and cathodic reaction rates, and the highest inhibition efficiency was 91.2%. The inhibitory effect of 5-chlorobenzotriazole is explained by the formation of the layer on the copper surface.

Preparation

4-Chloro-2-nitroaniline is used as raw material to produce 4-chloro-1,2-phenylenediamine by reduction of iron powder in acidic medium, and the latter is diazotized and cyclized to obtain 5-chlorobenzotriazole. The yield is 78%.
