Aniline

Aniline, phenylamine or aminobenzene is an organic compound with the formula C6H5NH2. Consisting of a phenyl group attached to an amino group, aniline is the prototypical aromatic amine. Like most volatile amines, it possesses the somewhat unpleasant odour of rotten fish. It ignites readily, burning with a smoky flame characteristic of aromatic compounds. Aniline is colourless to slightly yellow, but it slowly oxidises and resinifies in air, giving a red-brown tint to aged samples. [1] Aniline does not readily evaporate at room temperature and is slightly soluble in water and mixes readily with most organic solvents. [1,2]
