2,6-Dichloro-4-nitroaniline

2,6-Dichloro-4-nitroaniline is an organic compound with the formula O2NC6H2Cl2NH2. It is the most widely discussed isomer of dichloronitroaniline, mainly as a precursor to the azo dye disperse brown 1. It is prepared by treatment of 4-nitroaniline with a mixture of hydrochloric acid and hydrogen peroxide (a source of chlorine).[3][4]
