DEFINITION

Classification: 524/323

Aryl-OH or salt or aryl-o-metal bond DNRM:

(under subclass 81) Subject matter wherein the organic designated nonreactant material is (a) a phenolic compound containing a hydroxyl group directly attached to the nuclear carbon of an aryl group or its salt, or (b) a compound containing an aryl-O-M (M-metal) group, e.g., aryl-O-Pb-O-, etc.

(1) Note. A cyclic salt of a phenolic compound, e.g., etc., is not considered a heterocyclic ring system and therefor is properly classified here. [figure]

(2) Note. See the Class 520 Glossary for a definition of the term "metals".
