Class Information
Number: 544/236
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.) > Polycyclo ring system having a 1,2-diazine ring as one of the cyclos > Bicyclo ring system having the 1,2-diazine ring as one of the cyclos > At least three ring nitrogens in the bicyclo ring system
Description: Compounds wherein the bicyclo ring system includes at least one ring nitrogen in addition to the two ring nitrogens of the six-membered hetero ring.
