Andrievsky, Alexander M.; Lomzakova, Vera I.; Grachev, Mikhail K.; Gorelik, Mikhail V. published an article about the compound: 3-Bromo-4-chloronitrobenzene( cas:16588-26-4,SMILESS:BrC1=C(C=CC(=C1)[N+](=O)[O-])Cl ).Safety of 3-Bromo-4-chloronitrobenzene. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:16588-26-4) through the article.
Action of bromine in concentrated nitric acid allows carrying out mono- and polybromination of moderately deactivated aromatic compounds 4-Chloronitrobenzene and isophthalic acid turnes into 3-bromo-4-chloronitrobenzene and 5-bromoisophthalic acid at reaction with bromine in concentrated nitric acid at 20°C whereas in absence of bromine in the same conditions 4-chloro-1,3-dinitrobenzene and 5-nitroisophthalic acid are formed accordingly. Presence of bromine in concentrated nitric acid changes nitrating capacity to brominating one. Terephthalic acid and phthalic anhydride at heating with bromine in concentrated nitric acid can be transformed to appropriating tetrabromo substituted compounds
