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 five-membered hetero ring, e.g. griseofulvin
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 five-membered hetero ring, e.g. griseofulvin
No child classifications to compare. This is a leaf node in both IPC and CPC.
