Class Information
Number: 544/320
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 six-membered having two or more ring hetero atoms of which at least one is nitrogen (e.g., selenazines, etc.) > The six-membered hetero ring consists of two nitrogens and four carbons (e.g., 1,2-diazines, etc.) > 1,3-diazines > Chalcogen bonded directly to diazine ring carbon > At 4- or 6-position > Nitrogen attached directly at 2-position by nonionic bonding
Description: Compounds wherein nitrogen is attached directly to the 2-position of the six-membered hetero ring by nonionic bonding.
