Chemical Structure
Description
2,5-Difluoro-3-(trifluoromethoxy)benzodifluoride (CAS 1803871-91-1) is a high-purity analytical reference standard with the molecular formula C8H3F7O and a molecular weight of 248.10 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2,5-Difluoro-3-(trifluoromethoxy)benzodifluoride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.10 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
