Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If including non-isomeric impurities >5%
Mixtures exceeding isomer purity fall to general 'other' aromatic esters.
If featuring primary amino groups
Oxygen-function amino-compounds classify later in 2922 per numerical order rule.
If for diagnostic lab reagents containing this
Composite lab reagents shift to Chapter 38 per exclusions.
