Dichloroaniline

Dichloroanilines are chemical compounds which consist of an aniline ring substituted with two chlorine atoms and have the molecular formula C6H5Cl2N. 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:

Compound name CAS# Chemical structure Melting point Uses
2,3-Dichloroaniline 608-27-5 20–25 °C (68–77 °F)[2]
2,4-Dichloroaniline 554-00-7 59–62 °C (138–144 °F)[3]
2,5-Dichloroaniline 95-82-9 47–50 °C (117–122 °F)[4] Precursor to dyes and pigments, such as Pigment Yellow 10[1]
2,6-Dichloroaniline 608-31-1 36–38 °C (97–100 °F)[5]
3,4-Dichloroaniline 95-76-1 69–71 °C (156–160 °F)[6]
3,5-Dichloroaniline 626-43-7 46–52 °C (115–126 °F)[7]
