five-membered rings with one nitrogen atom and either one oxygen atom or one sulfur atom in positions 1,3

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Biocides, pest repellants or attractants, or plant growth regulators containing heterocyclic compounds > having rings with nitrogen atoms and oxygen or sulfur atoms, as ring hetero atoms > five-membered rings with one nitrogen atom and either one oxygen atom or one sulfur atom in positions 1,3

CPC:

Biocides, pest repellants or attractants, or plant growth regulators containing heterocyclic compounds (containing cyclic anhydrides, cyclic imides A01N37/00; containing compounds of the formula [IMAGE cpc-sch-A01N-0942.gif] containing only one heterocyclic ring, wherein m>=1 and n>=0 and [IMAGE cpc-sch-A01N-0943.gif]is unsubstituted or alkylsubstituted pyrrolidine, piperidine, morpholine, thiomorpholine, piperazine or a polymethyleneimine with four or more CH2 groups, A01N33/00 - A01N41/12; containing cyclopropane carboxylic acids or derivatives thereof, e.g. esters having heterocyclic rings, A01N53/00) > having rings with nitrogen atoms and oxygen or sulfur atoms as ring hetero atoms > five-membered rings with one nitrogen atom and either one oxygen atom or one sulfur atom in positions 1,3

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

IPC defines codes here since 1980.
