More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other halogenated heterocyclic compounds
Halogenated heterocycles without pyrazole ring or photo use go to general 'other' category.
If in developer formulations for x-ray film
Ready-to-use radiographic developers containing this compound classify as photo chemicals.
If classified primarily as halogenated phenyl compound
Material emphasis on trichlorophenyl moiety could shift to halogenated hydrocarbons.
