Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If halide function dominates over organic groups
Chapter 28 chlorides; Chapter note (E) classifies acid halides with acids, but simple halides may shift if not organo-inorganic.
If for aryl halide classification ignoring arsenic
Halogenated aromatics in 2903 if arsenic not principal characteristic per Chapter notes.
