DEFINITION

Classification: 568/700

Hydroxy containing (H of- OH may be replaced by a group IA or IIA light metal):

(under subclass 300) Compounds which contain an -OH group or an -OM group, wherein M is a metal selected from Group I or II of the Periodic Table having a specific gravity less than 4 (i.e., Li, Na, K, Rb, Cs or Be, Mg, Ca, Sr, and Ba).

(1) Note. -OM containing compounds are classified with the corresponding hydroxy containing compounds in the absence of a specific subclass providing for them. Subclass 851 is a specific subclass which provides for -OM containing compounds and, consequently, there are not any -OM containing compounds in subclasses 852 through 923.
