Preparation
4-Chloroaniline is not prepared from aniline, which tends to overchlorinate. Instead, it is prepared by reduction of 4-nitrochlorobenzene, which in turn is prepared by nitration of chlorobenzene.[4]
Uses
4-Chloroaniline is used in the industrial production of pesticides, drugs, and dyestuffs. It is a precursor to the widely used antimicrobial and bacteriocide chlorhexidine and is used in the manufacture of pesticides, including pyraclostrobin, anilofos, monolinuron, and chlorphthalim.[5]
4-Chloroaniline exhibits antimicrobial action against some bacteria and molds.[4]
