Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derivative with additional carboxy group
Carboxamide-function compounds (2924) take precedence over amine-functions per numerical order rule in Chapter 29.
If halogenated without nitrogen-function dominance
Halogenated acyclic hydrocarbons (2903) if nitrogen not principal function; Chapter notes prioritize last numerical heading.
If packaged as finished anticancer medicament
Medicaments in measured doses (3003) exclude bulk APIs; Chapter 29 limited to separate compounds, not formulated drugs.
