with hydrocarbon radicals, substituted by singly bound oxygen or sulphur atoms

Introduced: July 1974

Title

Titles differ between systems:

IPC: with hydrocarbon radicals, substituted by singly bound oxygen or sulfur atoms

CPC: with hydrocarbon radicals, substituted by singly bound oxygen or sulphur atoms

Full Title

Full titles differ between systems:

IPC:

Heterocyclic compounds containing hydrogenated pyridine rings, not condensed with other rings > with only hydrogen or carbon atoms directly attached to the ring nitrogen atom > having no double bonds between ring members or between ring members and non-ring members > with hydrocarbon or substituted hydrocarbon radicals directly attached to ring carbon atoms > with substituted hydrocarbon radicals attached to ring carbon atoms > with hydrocarbon radicals, substituted by singly bound oxygen or sulfur atoms

CPC:

Heterocyclic compounds containing hydrogenated pyridine rings, not condensed with other rings > with only hydrogen or carbon atoms directly attached to the ring nitrogen atom > having no double bonds between ring members or between ring members and non-ring members > with hydrocarbon or substituted hydrocarbon radicals directly attached to ring carbon atoms > with substituted hydrocarbon radicals attached to ring carbon atoms > with hydrocarbon radicals, substituted by singly bound oxygen or sulphur atoms

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 1974.
