General description
N-Methyl-2-nitroaniline is a solvatochromic dye.
Application
N-Methyl-2-nitroaniline was used in the determination of the polarities of ionic liquids using the Kamlet-Taft empirical polarity scales. It was also employed in characterization of the octadecyl-derivatized silica stationary phase and the corresponding mobile phases used in reversed-phase liquid chromatography.
