Chemical Structure
Description
The molecular framework of 3-Hydroxy-3-phenyl-3,4-dihydro-1H-pyrido[2,1-c][1,4]oxazin-5-ium bromide (C14H14NO2Br) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 3-Hydroxy-3-phenyl-3,4-dihydro-1H-pyrido[2,1-c][1,4]oxazin-5-ium bromide (CAS 902172-67-2), a certified reference material (molecular formula C14H14NO2Br, MW 308.18 g/mol) for analytical method development and quality control.
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.
