2-((4-(4-Methoxyphenyl)-8-methyl-2-oxo-2h-chromen-7-yl)oxy)acetic acid CAS 384362-18-9

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.

2-((4-(4-Methoxyphenyl)-8-methyl-2-oxo-2h-chromen-7-yl)oxy)acetic acid (CAS 384362-18-9) is a high-purity analytical reference standard with the molecular formula C19H16O6 and a molecular weight of 340.33 g/mol.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 2-((4-(4-Methoxyphenyl)-8-methyl-2-oxo-2h-chromen-7-yl)oxy)acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
