DEFINITION

Classification: 522/36

Containing two or more ketone groups:

(under subclass 33) Subject matter wherein the ketone compound contains at least two ketone groups.

(1) Note. For purposes of this class, a compound containing a -CC group, wherein * is two or more, is considered as being a plural ketone containing compound. Additionally, a compound containing a -CCC- group is considered as having two ketone groups may be part of a ring system as long as another ketone group is present which is acyclic.
