The IUPAC nomenclature for naming amines involves identifying the longest carbon chain attached to the nitrogen atom and using the suffix '-amine'.
For simple amines, the alkyl groups attached to the nitrogen are named as prefixes followed by the word 'amine'.
When the amine is not the principal functional group, the prefix 'amino-' is used before the name of the organic compound.
For secondary and tertiary amines, N is used to designate the groups attached to the nitrogen (e.g., N-methylpropanamine). The names of the alkyl groups are listed in alphabetical order if there is more than one type of alkyl group.
For cyclic amines, the prefix 'cyclo' is used before the alkyl portion, and the nitrogen atom is assumed to be at position 1 unless otherwise specified.
