DIFF Subgroup
C07D 213/06 containing only hydrogen and carbon atoms in addition to the ring nitrogen atom
Introduced: July 1974
Full Title
Heterocyclic compounds containing six-membered rings, not condensed with other rings, with one nitrogen atom as the only ring hetero atom and three or more double bonds between ring members or between ring members and non-ring members > having three double bonds between ring members or between ring members and non-ring members > having no bond between the ring nitrogen atom and a non-ring member or having only hydrogen or carbon atoms directly attached to the ring nitrogen atom > containing only hydrogen and carbon atoms in addition to the ring nitrogen atom
IPC and CPC are identically structured here. All 6 subcodes exist in both systems.
