3,5-Dibromaniline is a chemical compound that belongs to both the anilines and the halogen aromatic compounds .

presentation

3,5-Dibromaniline is prepared from 4-nitroaniline , which is first brominated with hydrochloric acid and elemental bromine in positions 2 and 6. Then it is deaminated to 3,5-dibromonitrobenzene and the end product is finally synthesized by reduction with iron and dilute sulfuric acid.
