1-CHLOROBENZOTRIAZOLE Chemical Properties,Usage,Production
Chemical Properties
White Solid
Uses
Oxidation and chlorination reagent.
Application
Used as positive halogen reagent for mild oxidations and selective chlorinations.
Synthesis
1-Chlorobenzotriazole is prepared by treat benzotriazole with sodium hypochlorite in 50% aq acetic acid. The reagent quickly precipitates and is obtained in nearly quantitative yield after recrystallization from CH2Cl2/petroleum ether.
storage
1-Chlorobenzotriazole may ignite spontaneously; reacts explosively with DMSO; light sensitive; stable to air and moisture in brown bottles; storage recommended at 0 °C; discard or repurify if discoloration occurs. This reagent should be handled in a fume hood.
