953.2 - Names of individual compounds RC(NH2)=N-NH2 or RC(=NH)-NH-NH2 are derived from the systematic names of the corresponding acids by replacing "-oic acid" by "-amide hydrazone" or "-ohydrazide imide", respectively, by replacing "-carboxylic acid" by "-carboxamide hydrazone" or "-carbohydrazide imide", respectively, or by replacing "-ic acid" by "-amide hydrazone" or "-ohydrazide imide", respectively. If the position of the double bond is unknown the compounds are named similarly but with the ending "-amidrazone".
953.3 - For N-substituted amidrazones, where the position of the double bond is known, the substituents receive locants laid down in preceding rules for amides, imides, hydrazides, and hydrazones. When the position of the double bond is unknown, primes are assigned in accordance with the system N''-CR-N'-N.
Examples to Rule C-953.2
Benzamidrazone: the name for a compound which may have one or other of the above two structures.
