Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If considered primarily imine or amine derivative
Saturated imino acids classified in 2925, but primary amino alcohols with oxygen function stay in 2922.
If as laboratory reagent kit component
Diagnostic reagents containing these compounds fall under Chapter 38, not pure chemicals.
