3-(4-Acetoxy-2-(prop-1-en-2-yl)-2,3-dihydrobenzofuran-5-carbonyl)-5,6-dimethoxybenzofuran-2-carboxylic acid CAS 5532-32-1

Description

The occurrence of 3-(4-Acetoxy-2-(prop-1-en-2-yl)-2,3-dihydrobenzofuran-5-carbonyl)-5,6-dimethoxybenzofuran-2-carboxylic acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(4-Acetoxy-2-(prop-1-en-2-yl)-2,3-dihydrobenzofuran-5-carbonyl)-5,6-dimethoxybenzofuran-2-carboxylic acid (CAS 5532-32-1), a certified reference material (molecular formula C25H22O9, MW 466.44 g/mol) for analytical method development and quality control.

3-(4-Acetoxy-2-(prop-1-en-2-yl)-2,3-dihydrobenzofuran-5-carbonyl)-5,6-dimethoxybenzofuran-2-carboxylic acid (C25H22O9) 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).

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.
