storage method

none

synthesis method

it is made from 4-chloro-2-nitroaniline by reducing iron powder in acidic medium. 1,2-phenylenediamine, the latter is diazotized and cyclized to obtain 5-chlorobenzotriazole. the yield is 78%.

purpose

used in organic synthesis and used as electroplating additives.
