Chemical Structure
Description
The occurrence of 2-(Difluoromethoxy)-1,4-difluorobenzene is closely related to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(Difluoromethoxy)-1,4-difluorobenzene (CAS 1404193-91-4) is a high-purity analytical reference standard with the molecular formula C7H4F4O and a molecular weight of 180.10 g/mol.
2-(Difluoromethoxy)-1,4-difluorobenzene (C7H4F4O) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
