2,5-DICHLORO-4-NITROANILINE Usage And Synthesis
Chemical Propertiesyellow powder
Uses2,5-Dichloro-4-nitroaniline may be employed as an indicator for the estimation of acidity of strong acids.
General Description2,5-Dichloro-4-nitroaniline is primary aniline indicator. Its pKa in sulfonate and water are -2.12 and -1.78, respectively.
Purification MethodsRecrystallise it from EtOH, then sublime it in vacuo.[Beilstein 12 H 735, 12 II 400.]
