Description
2-(3,4-Dihydroxy-phenyl)-5,7-dihydroxy-3-methoxy-8-((E)-3-methyl-but-2-enyl)-6-(3-methyl-but-2-enyl)-1-benzopyran-4-one 2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-3-methoxy-6,8-bis(3-methylbut-2-enyl)chromen-4-one 99217-70-6 Broussoflavanol B (CAS 99217-70-6), molecular formula C26H28O7 and molecular weight 452.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3,4-Dihydroxy-phenyl)-5,7-dihydroxy-3-methoxy-8-((E)-3-methyl-but-2-enyl)-6-(3-methyl-but-2-enyl)-1-benzopyran-4-one 2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-3-methoxy-6,8-bis(3-methylbut-2-enyl)chromen-4-one 99217-70-6 Broussoflavanol B (C26H28O7) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
