2,3-Dichloroaniline is an organic compound with the formula C₆H₃Cl₂(NH₂). It is one of several isomers of dichloroaniline. It is a colorless oil although commercial samples often appear colored. It is produced by hydrogenation of 2,3-dichloronitrobenzene.^[2]

Safety and environmental aspects

Its 72-h EC50 is 6.75 mg/L.^[3] Biodegradation of 2,3-dichloroaniline proceeds via initial ring hydroxylation.^[4]
