3-(3-(4-Ethoxyphenyl)-4-oxo-3,4-dihydroquinazolin-2-yl)propanoic acid CAS 554440-09-4

Description

Compared with other compounds in its class, the molecular weight of 338.36 g/mol gives 3-(3-(4-Ethoxyphenyl)-4-oxo-3,4-dihydroquinazolin-2-yl)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(3-(4-Ethoxyphenyl)-4-oxo-3,4-dihydroquinazolin-2-yl)propanoic acid (CAS 554440-09-4) is a high-purity analytical reference standard with the molecular formula C19H18N2O4 and a molecular weight of 338.36 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 3-(3-(4-Ethoxyphenyl)-4-oxo-3,4-dihydroquinazolin-2-yl)propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 338.36 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).

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.
