Introduced: January 1980
Full Title
Full titles differ between systems:
IPC:
Preparation of heterocyclic carbon compounds with only O, N, S, Se, or Te as ring hetero atoms > Oxygen as only ring hetero atoms > containing a hetero ring of at least seven ring members, e.g. zearalenone, macrolide aglycons
CPC:
Preparation of heterocyclic carbon compounds with only O, N, S, Se or Te as ring hetero atoms (C12P13/04 - C12P13/24 take precedence) > Oxygen as only ring hetero atoms > containing a hetero ring of at least seven ring members, e.g. zearalenone, macrolide aglycons
No child classifications to compare. This is a leaf node in both IPC and CPC.
