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.
