Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If industrial nitroaromatic use
If nitro function emphasized over hydrazine for end-use, could align with nitrobenzene derivatives.
If diagnostic or lab reagent kits
Composite lab reagents exclude from Chapter 29.
If heterocyclic ring forms
Heterocyclic compounds in 2933 take later numerical precedence.
