Dichloroaniline

Dichloroanilines are chemical compounds which consist of an aniline ring substituted with two chlorine atoms. There are six isomers of dichloroaniline. As aniline derivatives, they are named with the amino group in position 1. They are all colorless, although commercial samples can appear colored due to the presence of impurities. Several derivatives are used in the production of dyes and herbicides.^[1]

The six isomers are:

• 2,3-Dichloroaniline, CAS#608-27-5, m.p. 24 °C
• 2,4-Dichloroaniline, CAS#554-00-7, m.p. 63 °C
• 2,5-Dichloroaniline, CAS#95-82-9, m.p. 50 °C
• 2,6-Dichloroaniline, CAS#608-31-1, m.p. 39 °C
• 3,4-Dichloroaniline, CAS#95-76-1, m.p. 72 °C
• 3,5-Dichloroaniline, CAS#626-43-7, m.p. 51 °C
