| Halogenation occurs readily with aniline by electrophilic aromatic substitution. |
| Predominantly in the tangential walls, primary pit fields of high density are conspicuously labelled by aniline blue staining of callose. |
| By 1860, the recipe for magenta was accidentally altered by Charles Girard and Georges de Laire to produce aniline blue. |
| Nitrobenzene, which is used in the production of aniline, a major chemical intermediate in the production of dyes. |
| Paul Ehrlich improved on Koch's staining procedure, using aniline instead of ammonia and fuchsin instead of methylene blue. |
| Other uses of aniline include the manufacture of rubber processing chemicals and the production of agrochemicals and dyestuffs. |
