DIFF Subgroup
C07C 255/32

having cyano groups bound to acyclic carbon atoms of a carbon skeleton containing at least one six-membered aromatic ring

Introduced: January 1990

Full Title

Full titles differ between systems:

IPC:

Carboxylic acid nitriles > having cyano groups bound to acyclic carbon atoms > having cyano groups bound to acyclic carbon atoms of a carbon skeleton containing at least one six-membered aromatic ring

CPC:

Carboxylic acid nitriles (cyanogen or compounds thereof C01C3/00) > having cyano groups bound to acyclic carbon atoms > having cyano groups bound to acyclic carbon atoms of a carbon skeleton containing at least one six-membered aromatic ring

IPC and CPC are identically structured here. All 9 subcodes exist in both systems.

IPC defines codes here since 1990.
