Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by amine function
Dispute possible if aldehyde not deemed principal function, but oxygen-function amino-compounds specified.
If for unsubstituted benzaldehyde derivatives
Simple aldehydes classify in 2912, but amino substitution moves to later 2922 per numerical order.
If diagnostic reagent kit component
Prepared reagents for lab analysis shift to Chapter 38 per exclusions.
