The formula
C6H7N
Aniline is an organic compound with the formula C6H5NH2. Consisting of a phenyl group attached to an amino group, aniline is the prototypical aromatic amine. Its main use is in the manufacture of precursors to polyurethane and other industrial chemicals. Like most volatile amines, it has the odour of rotten fish. It ignites readily, burning with a smoky flame characteristic of aromatic compounds.
