Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If aromatic polycarboxylic acid form
Aromatic vs acyclic structure determines subchapter classification.
If partially esterified
Partial esters classify as alcohols with oxygen function, not parent acids.
If amino acid derivatives
Nitrogen function addition moves to Chapter 29 amino compounds heading.
