General description

2,5-Dimethylaniline is a colorless to dark yellow and colorless to brown liquid. It is a substrate for fungal laccases. 2,5-Dimethylaniline undergoes electrochemical oxidation in anhydrous NH4F·2.35 HF medium to form conducting polymer, poly(2,5-dimethylaniline). Poly(2,5-dimethylaniline) coating on copper substrate protects the Cu against corrosion. The Fourier transform infrared (FTIR) and Raman spectra of 2,5-dimethylaniline was studied. It induced transcription of lccIV.

Application

2,5-Dimethylaniline was used in the synthesis of nanocomposite of multi-walled carbon nanotubes embedded in poly(2,5-dimethylaniline). 2,5-Dimethylaniline was used to study the effect of metabolites formed from 2,5-xylidine by fungi on laccase activity.
