Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as a derivative salt
Salts of the polyamine would fall under the earlier derivative salts subheading per chapter classification rules.
If aromatic monoamine impurity dominates
Material composition shifts if primarily a monoamine rather than polyamine structure.
If containing organo-sulfur impurities
Presence of sulfur directly linked to carbon moves it to organo-sulfur compounds per chapter notes.
