DIFF Subclass Not Allocatable
C07C

ACYCLIC OR CARBOCYCLIC COMPOUNDS

Introduced: September 1968

Description

C07C covers the synthesis, preparation, and chemical composition of acyclic (open-chain) and carbocyclic organic compounds containing only carbon and hydrogen, or carbon, hydrogen, and non-metallic elements in their basic structure. This broad subclass encompasses hydrocarbons, alcohols, aldehydes, ketones, carboxylic acids, esters, and related derivatives of aliphatic and cyclic carbon skeletons. The classification explicitly excludes heterocyclic compounds (which contain atoms other than carbon in the ring structure), which are covered separately in C07D, and naturally occurring or isolated compounds typically classified elsewhere by their specific function or source.

Of 123 combined children, 113 exist in both systems.

10 codes are CPC-only extensions.

Note: 10 CPC extensions are marked as secondary classification only.

38 shared codes have differing titles between IPC and CPC.
