Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) [6] is an organic compound with the formula C 6 H 5 NH 2. Consisting of a phenyl group ( −C 6 H 5 ) attached to an amino group ( −NH 2 ), aniline is the simplest aromatic amine .
Aniline is a benzenoid compound. The NH 2 group attached to the benzene ring means that there is a lone pair of electrons that can enter into conjugation with the benzene ring resulting in delocalization in the aniline. Aniline absorbs in the K (220 - 250 nm) and the B (250 - 290 nm) bands exhibited by benzenoid compounds.

In the industrial production, MDA is produced by reaction of formaldehyde and aniline in the presence of hydrochloric acid. [3] MDA is a common monomer in the synthesis of polymer materials. These include polyamides, [4] polyimides and polyimines. [5] MDA is also used extensively as a precursor to methylene diphenyl diisocyanate (MDI).

Space-filling model of the local structure of a polyaniline chain in the reduced leucoemeraldine base (LEB) oxidation state, based on the crystal structure of the tetramer. [1] Polyaniline (PANI) is a conducting polymer and organic semiconductor of the semi-flexible rod polymer family. The compound has been of interest since the 1980s because ...
Mauveine, also known as aniline purple and Perkin's mauve, was one of the first synthetic dyes. [ 1 ] [ 2 ] It was discovered serendipitously by William Henry Perkin in 1856 while he was attempting to synthesise the phytochemical quinine for the treatment of malaria . [ 3 ]
