Basic information of amines

Amines, which are derivatives of ammonia, are basic organic chemicals and functional groups that contain a basic nitrogen atom with a lone pair. Inorganic derivatives of ammonia are also called amines, such as chloramine (NClH2).
Compounds with the nitrogen atom attached to a carbonyl of the structure R-C(=O)NR2 have different chemical properties from amines, and they are called amides.
Primary aromatic amines are used as a starting material for the manufacture of azo dyes. It reacts with nitri(III) acid to form diazonium salt, which can undergo coupling reaction to form azo compound. As azo-compounds are highly coloured, they are widely used in dyeing industries.
