Located the subject Hydrogen then
Peroxide Class / subclass is 423 /
584 Hyperlinks to Manual of
Classification
17
Step 2 Class 423, Chemistry of Inorganic
Compounds
Class 423 hyperlink to definition of class
18
Note the Manuals Hierarchical Setup
Scanning down the schedule we find the
appropriate peroxide by following the schedule
hierarchy from least specific to most specific
Subclass 584 looks good Check its definition
using the hyperlink
