Chemical Structure
Description
The occurrence of 1,3-Dichloro-2-difluoromethoxy-4-fluorobenzene is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3-Dichloro-2-difluoromethoxy-4-fluorobenzene (CAS 1804516-64-0) is a high-purity analytical reference standard with the molecular formula C7H3Cl2F3O and a molecular weight of 231.00 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 1,3-Dichloro-2-difluoromethoxy-4-fluorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
