Class Information
Number: 548/521
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Heterocyclic carbon compounds containing a hetero ring having chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) or nitrogen as the only ring hetero atoms (class 540, subclass 1) > Hetero ring is five-membered consisting of one nitrogen and four carbons (e.g., halopyrrolidines, etc.) > Additional hetero ring, which is attached directly or indirectly to the five-membered hetero ring by nonionic bonding > The additional hetero ring also contains nitrogen > Ring carbon of each of the two nitrogen containing hetero rings is bonded directly to chalcogen (e.g., both rings may be bonded to the same oxygen atom or to different oxygen atoms, etc.) > Plural chalcogens bonded directly to ring carbons of each of the two nitrogen containing hetero rings (e.g., bis-succinimides, etc.) > Double bond between ring carbons in each of the two nitrogen containing hetero rings (e.g., bis-maleimides, etc.)
Description: Compounds wherein there is a double bond between ring carbons in each of the two nitrogen containing hetero rings.
