General description

Diphenylamine, a secondary aromatic amine, is an N-substituted derivative of aniline.

Application

Diphenylamine may be used in the preparation of diphenylamine reagent, which is employed for the quantitative estimation of nucleic acid (DNA) from various biological sources by colorimetric method. It may be used in the preparation of poly(diphenylamine), via electrochemical and chemical polymerization methods. It can also be used as an internal standard in the determination of hair nicotine via gas chromatography coupled with mass spectrometry.
