General description
2-Methoxy-5-methylaniline is an aromatic amine present as contaminants in commercial hair dye samples.
Application
2-Methoxy-5-methylaniline was used in the synthesis of 4-(4-Amino-5-methoxy-2-methylphenylazo)-5-hydroxy-naphthalene-2,7-disulfonic acid. 2-Methoxy-5-methylaniline was used to analyse the application of polymeric ionic liquids as selective solid-phase microextraction sorbent coatings for the analysis of genotoxic impurities and structurally alerting compounds such as alkyl halides and aromatics. 2-Methoxy-5-methylaniline was used in a study to develop a sensitive analytical method for the determination of aromatic amines found in commercial hair dyes using high liquid chromatography coupled to an electrochemical detector by using the ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide in the mobile phase.
