3-(3,5-Difluorophenyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine (CAS 1707571-76-3) is a high-purity analytical reference standard with the molecular formula C14H11F2NO and a molecular weight of 247.24 g/mol.
The molecular framework of 3-(3,5-Difluorophenyl)-3,4-dihydro-2H-benzo[b][1,4]oxazine (C14H11F2NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
