CAS:2,4-Dibromo-6-nitroaniline is a nitro compound that has been used in the production of dyes. It is also used as a component in the synthesis of other organic compounds. 2,4-Dibromo-6-nitroaniline can be produced by electrolysis of an acid solution containing radical cations and benzene. The radical cations are formed by proton transfer from the acid to the benzene, followed by electron transfer from benzene to the electrode. This process results in the formation of nitro groups on the benzene ring, which undergoes oxidation to form 2,4-dibromo-6-nitroaniline. The cyclic voltammetry shows that this process occurs via two pathways: one with a fast rate and one with a slow rate. The mechanism for this reaction is not yet known.
