DEFINITION

Classification: 514/529

Z-C(=O)-O-Y wherein Z is hydrogen or an organic radical bonded to the C(=O) by a carbon and Y is an organic radical bonded to the oxygen by a carbon:

(under subclass 506) Subject matter wherein the ester is derived from a carboxylic acid of the formula ZO-Y wherein the Z and Y are organic radicals directly bonded by carbon atoms or Z is a hydrogen atom.

(1) Note. This subclass contains, for example: [figure] [caption], etc.

(2) Note. A compound which contains plural radicals, is proper for the subclass hereunder if the Z (or Y) of any one of the radicals meets the requirements for Z (or Y) in the subclass.
