The following is an example of trivial names which are retained:
Examples to Rule C-812.1
813.2 - Primary diamines and polyamines in which the amino groups are attached to a heterocyclic nucleus itself containing nitrogen are named by adding (a) the suffix "-diamine", "-triamine", etc., to the name of the parent compound, or (b) the prefix "diamino-", "triamino-", etc., to the name of the parent compound.
813.3 - Primary diamines and polyamines where all the amino groups are attached to identical side chains linked to a cyclic nucleus are named (a) by conjunctive nomenclature or (b) as aminoalkyl derivatives of the cyclic parent.
Examples to Rule C-813.2
813.4 - When primary diamines and polyamines contain amino groups in different side chains linked to a cyclic nucleus, then (a) the senior side chain or side chains are named by conjunctive nomenclature and the remainder as prefixes, or (b) all the side chains are named by means of prefixes.
