Class Information
Number: 548/300.1
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 having two or more ring hetero atoms of which at least one is nitrogen (e.g., selenazoles, etc.) > 1,3-diazoles (including hydrogenated)
Description: Compounds wherein nitrogen atoms occupy the 1 and 3 positions and carbon atoms occupy the remaining three positions of the five-membered hetero ring.
