Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for halogenated alcohols if hydroxyethyl group predominates
Halogenated derivatives might classify under oxygen-function compounds if sulfonamide secondary.
If when supplied with added stabilizers for transport
Chapter note (f) allows stabilizers, but excessive additives shift to chemical preparations.
