Description and Uses
m-Chloroaniline is used as an intermediate for pesticides, pharmaceuticals, and dyes. It is produced by lowpressure hydrogenation of 3-chloronitrobenzene in the liquid phase with noble metal and/or noble metal sulfide catalysts. The addition of metal oxides to the reaction helps avoid dehalogenation. The yield is approximately 98 %.
3-Chlorobenzenamine is used in the synthesis of pyrimidoazepine analogs as serotonin 5-HT2A and 5-HT2C receptor ligands for the treatment of obesity. Also used in the synthesis of novel COX-2 inhibito rs.
