Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used primarily as hormone antagonist
Chapter note (b) to 2937 includes hormone derivatives/analogues, later heading takes precedence.
If nitrogen-function dominates over amide
Certain nitrogenous compounds classify under 2929 if nitro/nitroso not considered amide per note.
If ester of carbamic acid present
Esters of acid-function compounds classify with later numerical order per note (A).
