Hydrazines and Their Derivatives
Rule C-923 923.1 - Compounds X=N-N=X are named by one of the following methods: (a) by adding the word "azine" after the name of the
corresponding aldehyde or ketone when no other group is present having priority for citation as principal group; or (b) by use of the prefix "azino-" for the radical =N-N= and the
nomenclature for assemblies of identical units (see Subsection C-0.7) when the group X contains a substituent having priority for citation as principal group.
923.2 - Compounds X=N-N=Y (where X is different from Y) are named as hydrazones NH2NY substituted by an alkylidene, cycloalkylidene, or bivalent heterocyclic radical X=. The group Y
is that one of the pair X, Y that carries the substituent with priority for citation as suffix, or, if that is not decisive, is the senior.
