DEFINITION

Classification: 516/64

The compound contains -C(=O)OH or salt thereof:

(under subclass 58) Subject matter in which the organic* compound containing sulfoxy* also contains -C(=O)OH group or salt thereof.

(1) Note. "-C(=O)OH group or salt thereof" does NOT include carboxylic acid esters (-C(=O)OR where R is an organic* group).
