Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by carboxamide function rather than heterocycle
Functional group classification may supersede heterocyclic structure in some derivatives
If when containing organo-sulfur impurities affecting classification
Presence of sulfur directly linked to carbon shifts to organo-sulfur compounds per Chapter Note
If mixtures containing >5% solvents or stabilizers
Solutions or mixtures for transport exceeding purity threshold classify as preparations
