Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If emphasizing organo-sulfur function
Chapter notes direct organo-sulfur compounds to 2930 if sulfur is directly linked to carbon, potentially overriding amide classification.
If in salt form or diluted
Salts of amides classified with the base compound, but mixtures may shift to 'other' aromatic amides.
