Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If salt formation considered different heterocyclic structure
Some salt forms with complex counterions may classify as 'other' heterocyclics if structure significantly altered.
If guanidine salt rather than simple inorganic
Organic base salts follow the base or acid occurring last in numerical order per Chapter Note 3(C)(2).
