Nomenclature

If there is only one amino group, the compound can keep the name aniline. If there is more than one, the suffix amine is used (for example, phenylenediamine), and if there are other groups of higher priority, the NH2 is named with the prefix amino. Look at some examples:

Examples of aniline nomenclature: 3-ethylaniline, 4-nitroaniline, 3-chloro-5-methylaniline, o-, m- and p-phenylenediamine, 2-aminobenzoic and 3-aminobenzenesulfonic acids and 1,2,3- and 1,3,5-phenylenetriamine
