DEFINITION

Classification: 514/546

ZC(=O)OY, wherein Z is an acyclic radical bonded to the C=O by a carbon and Y is an organic radical bonded to the oxygen by a carbon:

(under subclass 529) Subject matter wherein Z is an acyclic directly bonded to the C+O by a carbon and Y is an organic radical directly bonded to the oxygen by a carbon.

(1) Note. This subclass contains, for example: CH3O-CH2[end subscrpt]-CH-C2H5[end subscrpt], etc.NO2
