Class Information
Number: 544/410
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.) > 1,4-diazines > Unsubstituted or hydrocarbyl substituted only, or salt thereof
Description: Compounds wherein the six-membered hetero ring is unsubstituted or is substituted only by radicals which consist of hydrogen and carbon, or salts thereof.
