C07F 9/576

Six-membered rings

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 one nitrogen atom as the only ring hetero atom > Six-membered rings

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 one nitrogen atom as the only ring hetero atom > Six-membered rings

Of 6 combined children, 5 exist in both systems.

1 codes are CPC-only extensions.
