C07F 9/6581

having phosphorus and nitrogen atoms with or without oxygen or sulfur atoms, as ring hetero atoms

Introduced: January 1990

Full Title

Full titles differ between systems:

IPC:

Compounds containing elements of Groups 5 or 15 of the Periodic Table > Phosphorus compounds > Heterocyclic compounds, e.g. containing phosphorus as a ring hetero atom > having phosphorus atoms, with or without nitrogen, oxygen, sulfur, selenium or tellurium atoms, as ring hetero atoms > having phosphorus and nitrogen atoms with or without oxygen or sulfur atoms, as ring hetero atoms

CPC:

Compounds containing elements of Groups 5 or 15 of the Periodic Table > Phosphorus compounds (sugar phosphates C07H11/04; nucleotides C07H19/00, C07H21/00; nucleic acids C07H21/00) > Heterocyclic compounds, e.g. containing phosphorus as a ring hetero atom > having phosphorus atoms, with or without nitrogen, oxygen, sulfur, selenium or tellurium atoms, as ring hetero atoms > having phosphorus and nitrogen atoms with or without oxygen or sulfur atoms, as ring hetero atoms

Of 5 combined children, 3 exist in both systems.

2 codes are CPC-only extensions.

2 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1990.
