Amides and Imides

Monoacylamines Rule C-822

822.1 - Names of primary amides in which the NH2 group is unsubstituted are derived from the systematic names of the corresponding acids by replacing "-oic acid" or "-ic acid" by "-amide" or "-carboxylic acid" by "-carboxamide". When trivial names of the acids are used which end in "-ic acid" this ending is replaced by "-amide". (cf. Rule C-971).

Examples to Rule C-822.1

The following abbreviated name is retained:

822.2 - For amides of amino acids having trivial names ending in "-ine", "-amide" or "-diamide" is added after the name of the acid, with elision of terminal "e" (for monoamides).

Examples to Rule C-822.2

Note: For monoamides of dicarboxylic acids see Rules C-421.3 and C-431.1.
