DEFINITION

Classification: 546/107

Plural nitrogens, other than as nitro or nitroso, attached directly to the carbocyclic rings of the acridine ring system (e.g., 3, 6-diaminoacridines, etc.):

(under subclass 104) Compounds wherein at least two nitrogens, except as members of the nitro (-NO) or nitroso (-NO) group, are attached directly to the carbocyclic rings of the acridine ring system.
