Chemical Structure
Description
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.
4-((2,3-Dihydro-2-methyl-3-oxobenzo[b][1,4]oxazin-4-yl)methyl)benzoic Acid (CAS 900706-47-0) is a high-purity analytical reference standard with the molecular formula C17H15NO4 and a molecular weight of 297.31 g/mol.
The molecular framework of 4-((2,3-Dihydro-2-methyl-3-oxobenzo[b][1,4]oxazin-4-yl)methyl)benzoic Acid (C17H15NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
