C07C 225/16 and containing six-membered aromatic rings
Introduced: January 1990
Full Title
Full titles differ between systems:
Compounds containing amino groups and doubly-bound oxygen atoms bound to the same carbon skeleton, at least one of the doubly-bound oxygen atoms not being part of a —CHO group, e.g. amino ketones > having amino groups bound to acyclic carbon atoms of the carbon skeleton > the carbon skeleton being unsaturated > and containing six-membered aromatic rings
Compounds containing amino groups and doubly—bound oxygen atoms bound to the same carbon skeleton, at least one of the doubly—bound oxygen atoms not being part of a —CHO group, e.g. amino ketones > having amino groups bound to acyclic carbon atoms of the carbon skeleton > the carbon skeleton being unsaturated > and containing six-membered aromatic rings
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
