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.

He developed the first commercially successful route to the dye called Aniline black. [5] [6] The first definitive report of polyaniline did not occur until 1862, which included an electrochemical method for the determination of small quantities of aniline. [7] From the early 20th century on, occasional reports about the structure of PANI were ...
DMA was first reported in 1850 by the German chemist A. W. Hofmann, who prepared it by heating aniline and iodomethane: [3] [4] C 6 H 5 NH 2 + 2 CH 3 I → C 6 H 5 N(CH 3) 2 + 2 HI. DMA is produced industrially by alkylation of aniline with methanol in the presence of an acid catalyst: [5] C 6 H 5 NH 2 + 2 CH 3 OH → C 6 H 5 N(CH 3) 2 + 2 H 2 O
Dibenzylaniline or N,N-Dibenzylaniline is a chemical compound consisting of aniline with two benzyl groups as substituents on the nitrogen.

2,4,6-Tribromoaniline is a brominated derivative of aniline with the formula C 6 H 4 Br 3 N. It is used in organic synthesis of pharmaceuticals, agrochemicals and fire-extinguishing agents. It is used in organic synthesis of pharmaceuticals, agrochemicals and fire-extinguishing agents.
Approximately 95% of nitrobenzene industrially produced is hydrogenated to aniline: [5] C 6 H 5 NO 2 + 3 H 2 → C 6 H 5 NH 2 + 2 H 2 O. Aniline is a precursor to urethane polymers, rubber chemicals, pesticides, dyes (particularly azo dyes), explosives, and pharmaceuticals. Most aniline is consumed in the production of methylenedianiline, a ...
