Two nitrogen atoms

Introduced: July 1974

Full Title

Full titles differ between systems:

IPC:

Heterocyclic compounds containing 1,3-diazine or hydrogenated 1,3-diazine rings > not condensed with other rings > having three or more double bonds between ring members or between ring members and non-ring members > with hetero atoms or with carbon atoms having three bonds to hetero atoms with at the most one bond to halogen, directly attached to ring carbon atoms > Two or more oxygen, sulfur or nitrogen atoms > Two nitrogen atoms

CPC:

Heterocyclic compounds containing 1,3-diazine or hydrogenated 1,3-diazine rings > not condensed with other rings > having three or more double bonds between ring members or between ring members and non-ring members > with hetero atoms or with carbon atoms having three bonds to hetero atoms with at the most one bond to halogen, directly attached to ring carbon atoms > Two or more oxygen, sulphur or nitrogen atoms > Two nitrogen atoms

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 1980.
