3,4-Dichloroaniline is an organic compound with the formula C6H3Cl2(NH2). It is one of several isomers of dichloroaniline. It is a white solid although commercial samples often appear gray.
Applications It is a precursor to dyes, agricultural chemicals, and drugs including the antimalarial chlorproguanil.
Herbicides include: propanil, linuron, DCMU, diuron, Anisuron, Neburon, Phenobenzuron.
On reaction with sodium ethoxide, it goes on to be used in the synthesis of diethofencarb.
Other notable uses include in the synthesis Eclanamine, Cericlamine & Nolinium.
Preparation It is produced by hydrogenation of 3,4-dichloronitrobenzene.
Safety and environmental aspects Being a precursor to some herbicides, the toxicity and fate of dichloroaniline is of interest. One pathway for the biodegradation of dichloroaniline is oxidation to the catechol derivatives.
