Compared with other compounds in its class, the molecular weight of 261.27 g/mol gives 3-(3,5-Difluorophenyl)-7-methyl-3,4-dihydro-2H-benzo[b][1,4]oxazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(3,5-Difluorophenyl)-7-methyl-3,4-dihydro-2H-benzo[b][1,4]oxazine (CAS 1707605-41-1), a certified reference material (molecular formula C15H13F2NO, MW 261.27 g/mol) for analytical method development and quality control.
The molecular framework of 3-(3,5-Difluorophenyl)-7-methyl-3,4-dihydro-2H-benzo[b][1,4]oxazine (C15H13F2NO) 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
