Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 198.21 g/mol gives 4-(3,5-Difluorophenyl)oxane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(3,5-Difluorophenyl)oxane (CAS 1395281-51-2), a certified reference material (molecular formula C11H12F2O, MW 198.21 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-(3,5-Difluorophenyl)oxane is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 198.21 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.
As a certified reference material (CRM), 4-(3,5-Difluorophenyl)oxane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
