2,4,6-Tribromoaniline is a brominated derivative of aniline with the formula C<sub>6</sub>H<sub>4</sub>Br<sub>3</sub>N. It is used in organic synthesis of pharmaceuticals, agrochemicals and fire-extinguishing agents.
2,4,6-Tribromoaniline can be prepared by treating bromine water with aniline in a solution of acetic acid or dilute hydrochloric acid:
Diazotization, then reaction with ethanol to replace the diazonium group with hydrogen, gives 1,3,5-tribromobenzene.
