Chemical Structure
Description
The molecular framework of 6,6'-((4-Methoxyphenyl)methylene)bis(5-hydroxy-2-(hydroxymethyl)-4H-pyran-4-one) (C20H18O9) 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).
6,6'-((4-Methoxyphenyl)methylene)bis(5-hydroxy-2-(hydroxymethyl)-4H-pyran-4-one) (CAS 96306-51-3) is a high-purity analytical reference standard with the molecular formula C20H18O9 and a molecular weight of 402.35 g/mol.
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.
As a certified reference material (CRM), 6,6'-((4-Methoxyphenyl)methylene)bis(5-hydroxy-2-(hydroxymethyl)-4H-pyran-4-one) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
