Description and Uses
p-Chloroaniline, 1-amino-4- chlorobenzene,is a white to light amber, crystalline solid at room temperature. It is used as an intermediate for pesticides, pharmaceuticals, pigments, and dyes. Production is similar to that of m-chloroaniline .
4-Chloroaniline is an important raw material in production of agricultural chemicals, azo dyes and pigments, cosmetics, and pharmaceutical products. It is used as an intermediate in the manufacture of chromophore AS-LB, as well as in pharmaceutical intermediates such as chlordiazepoxide and phena tincture. It is also an intermediate for the herbicide Anilofos, the insecticide chlorbenzuron and the plant growth regulator Inabenfide.
