Introduced: July 1974
Full Title
Full titles differ between systems:
Heterocyclic compounds containing five-membered rings having one sulfur atom as the only ring hetero atom > not condensed with other rings > not substituted on the ring sulfur atom > with only hydrogen atoms, hydrocarbon or substituted hydrocarbon radicals, directly attached to the ring carbon atoms
Heterocyclic compounds containing five-membered rings having one sulfur atom as the only ring hetero atom > not condensed with other rings > not substituted on the ring sulphur atom > with only hydrogen atoms, hydrocarbon or substituted hydrocarbon radicals, directly attached to the ring carbon atoms
IPC and CPC are identically structured here. All 5 subcodes exist in both systems.
IPC defines codes here since 1974.
