Chemical Structure
Description
5,7-Dihydroxy 3,3',4',5',6,8-hexamethoxyflavone (CAS 96887-18-2) is a high-purity analytical reference standard with the molecular formula C21H22O10 and a molecular weight of 434.39 g/mol.
5,7-Dihydroxy 3,3',4',5',6,8-hexamethoxyflavone (C21H22O10) 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.
CATO manufactures 5,7-Dihydroxy 3,3',4',5',6,8-hexamethoxyflavone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
