Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If solvent renders specific use suitability
Note (e) exclusion applies if solution designed for particular application.
If ethyl acetate solvent dominant
Ether-alcohol solvents may classify under their own headings.
If aqueous maleic acid solution
Hydrolyzed products classify as acids, not anhydrides.
