2,4,6-Trichloroaniline is a chemical compound with a formula of C<sub>6</sub>H<sub>4</sub>Cl<sub>3</sub>N. It is useful as an intermediate in chemical reactions.
2,4,6-Trichloroaniline can be prepared by reaction of dry aniline with chlorine gas while in an anhydrous solution of carbon tetrachloride. 2,4,6-Trichloroaniline precipitates from solution as a white solid. In the presence of water in the solution the white material will be contaminated with aniline black.
Occupational exposure to 2,4,6-trichloroaniline may occur through inhalation and dermal contact with this compound at workplaces where 2,4,6-trichloroaniline is produced or used (SRC). The general population may be exposed to 2,4,6-trichloroaniline via drinking water and dermal contact with this compound in dyestuffs, pigments, and pesticides containing 2,4,6-trichloroaniline. 2,4,6-trichloroaniline can be toxic when inhaled or ingested orally. The lethal dose is 2400 mg/kg for a rat.
Upon heating, 2,4,6-trichloroaniline will not undergo combustion, but may release hydrogen chloride, nitrogen oxides or carbon monoxide.
