Aniline is an organic compound with the formula C6H5NH2. Consisting of a phenyl group attached to an amino group, aniline is the simplest aromatic amine. It is an industrially significant commodity chemical, as well as a versatile starting material for fine chemical synthesis. Its main use is in the manufacture of precursors to polyurethane, dyes, and other industrial chemicals. Like most volatile amines, it has the odor of rotten fish. It ignites readily, burning with a smoky flame characteristic of aromatic compounds.
Chemically, it is considered an electron-rich benzene derivative, and as a consequence, reacts rapidly in electrophilic aromatic substitution reactions. Likewise, it is also prone to oxidation: while freshly purified aniline is an almost colorless oil, exposure to air results in gradual darkening of the sample (to yellow or red) due to the formation of strongly colored, oxidized impurities. Aniline can be diazotized to give a diazonium salt, which can then undergo various nucleophilic substitution reactions.

Aniline is one of the most important intermediates in the dye industry. In the dye industry, aniline can be used to produce acid ink blue G, acid medium BS, acid light yellow, direct orange S, direct pink, indigo, disperse yellow brown, cationic pink FG and reactive brilliant red X-SB. In terms of organic pigments, it is used to produce gold red, gold red G, big red powder, phenol cyanine red, oil-soluble black and so on. Used for aniline black dye in printing and dyeing industry; In the pesticide industry, it is used to produce many insecticides and fungicides such as DDV, weeding ether, toxoachamine, etc. Aniline is an important raw material of rubber auxiliaries, used in the manufacture of aging agent A, aging agent D, aging agent RD and 4010, accelerator M, 808, D and CA, etc. It can also be used as the raw material of medicine sulfanilamide and the intermediate of producing perfume, plastic, varnish, film, etc. It can also be used as stabilizer in explosives, explosion-proof agent in gasoline and solvent. Other can also be used to produce hydroquinone, 2-phenyl indoles, etc.
