Note(s)
In this subclass, tradenames that are often found in scientific and patent literature have been used in order to define precisely the scope of the groups [3,6,7]Attention is drawn to the definitions of groups of chemical elements following the title of section C Attention is drawn to Note (1) after class C01, which defines the last place priority rule applied in this class, i e in the range of subclasses C01B-C01G and within these subclasses Therapeutic activity of compounds is further classified in subclass A61P
