Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stabilizer renders it a chemical preparation rather than pure compound
Chapter note f limits stabilizers to preservation/transport; excess changes to mixtures.
If ethyl ester form rather than chloride
Heading specifically distinguishes benzenesulfonyl chloride from ethyl esters.
If containing sulfo and nitro groups
2904.10 limited to derivatives containing only sulfo groups.
