Chemical Structure
Description
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.
3-((4-Methoxybenzyl)oxy)-3-oxo-2-(4-((tetrahydro-2H-pyran-2-yl)oxy)phenyl)propanoic acid (CAS 70653-29-1) is a high-purity analytical reference standard with the molecular formula C22H24O7 and a molecular weight of 400.42 g/mol.
Based on its molecular formula C22H24O7, 3-((4-Methoxybenzyl)oxy)-3-oxo-2-(4-((tetrahydro-2H-pyran-2-yl)oxy)phenyl)propanoic acid contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 400.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
