DIFF Subgroup
C07C 255/01 having cyano groups bound to acyclic carbon atoms
Introduced: January 1990
Full Title
Full titles differ between systems:
IPC:
Carboxylic acid nitriles > having cyano groups bound to acyclic carbon atoms
CPC:
Carboxylic acid nitriles (cyanogen or compounds thereof C01C3/00) > having cyano groups bound to acyclic carbon atoms
IPC and CPC are identically structured here. All 14 subcodes exist in both systems.
IPC defines codes here since 1990.
