Chemical Structure

(Z)-(2-((2-(4-Methoxybenzylidene)-3-oxo-2,3-dihydrobenzofuran-6-yl)oxy)acetyl)-D-alanine CAS 956947-68-5 chemical structure

Description

(Z)-(2-((2-(4-Methoxybenzylidene)-3-oxo-2,3-dihydrobenzofuran-6-yl)oxy)acetyl)-D-alanine (CAS 956947-68-5) is a high-purity analytical reference standard with the molecular formula C21H19NO7 and a molecular weight of 397.38 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (Z)-(2-((2-(4-Methoxybenzylidene)-3-oxo-2,3-dihydrobenzofuran-6-yl)oxy)acetyl)-D-alanine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 397.38 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.
