CATO supplies 2-(3,4-Dimethoxybenzylidene)-6-hydroxybenzofuran-3(2h)-one (CAS 32396-83-1), a certified reference material (molecular formula C17H14O5, MW 298.29 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3,4-Dimethoxybenzylidene)-6-hydroxybenzofuran-3(2h)-one (C17H14O5) is characterized by a flavonoid core, 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.
