4-Chloroaniline is a organochlorine compound with the formula ClC6H4NH2. This pale yellow solid is one of several known chloroanilines.


4-Chloroaniline is not prepared from aniline, which tends to overchlorinate. Instead, it is prepared by hydrogenation of 4-nitrochlorobenzene, which in turn is prepared by nitration of chlorobenzene.[2]

4-Chloroaniline is a precursor to the widely used antimicrobial and bacteriocide Chlorhexidine.
