Chemical Structure
Description
3-(7-Methoxy-4,8-dimethyl-2-oxo-2H-chromen-3-yl)-propanoic acid (C15H16O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 3-(7-Methoxy-4,8-dimethyl-2-oxo-2H-chromen-3-yl)-propanoic acid (CAS 701965-63-1), a certified reference material (molecular formula C15H16O5, MW 276.28 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.
