REACH registered substance: 5-bromo-2-chlorobenzoic acid (EC: 244-558-5)
Description5-Bromo-2-chlorobenzoic acid (BCBA) is an organic reagent that can be used in electroinduced dehalogenation reactions. Ag/Cu electrodes exhibit high electrocatalytic activity in the dehalogenation reaction of BCBA. The process is characterised by a sequence of halide excretion and hydrogen addition. Since the bond dissociation energy value of C-Br bond is smaller than that of C-Cl bond, Br-w is more easily released from the benzene ring. As C-Br breaks, BCBA gains electrons and hydrogen to form the intermediate 2-chlorobenzoate. C-Cl then breaks in the same way to give the final product benzoate.
Uses5-Bromo-2-chlorobenzoic acid was used to evaluate the homogeneity of organic powder. It can be used to produce 2-chloro-5-deuteriobenzoic acid.
