2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl thiophene-2-carboxylate CAS 331460-15-2

Description

Compared with other compounds in its class, the molecular weight of 378.40 g/mol gives 2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl thiophene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl thiophene-2-carboxylate (CAS 331460-15-2), a certified reference material (molecular formula C21H14O5S, MW 378.40 g/mol) for analytical method development and quality control.

The molecular framework of 2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl thiophene-2-carboxylate (C21H14O5S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.
