Class Information
Number: 548/518
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
Description: Compounds wherein nitrogen is a ring member of the additional hetero ring.
