WebIt is an organic compound, a derivative of aniline. It is used as a component of engineering polymers and composites, and an ingredient in hair dyes. 4-Phenylenediamine is a precursor to aramid plastics and fibers such as Kevlar and Twaron. 4-Phenylenediamine is a common hair dye. The nearly colourless dye precursor oxidizes to the dye. WebThe nitrogen of methyl amine has a significant amount of electron density on its nitrogen, shown as a red color, which accounts for it basicity compared to aniline. While the electron density of aniline's nitrogen is delocalized in the aromatic ring making it less basic. Basicity of Substituted Arylamines
