Description

CATO supplies 5,2'-dihydroxy-6,7,8,6'-tetramethoxyflavone 5-hydroxy-2-(2-hydroxy-6-methoxy-phenyl)-6,7,8-trimethoxy-chromen-4-one 5-hydroxy-2-(2-hydroxy-6-methoxyphenyl)-6,7,8-trimethoxy-4H-1-benzopyran-4-one 55084-08-7 CHEBI:9061 neobaicalein scullcapflavone II skullcapflavone II (CAS 55084-08-7), a certified reference material (molecular formula C19H18O8, MW 374.34 g/mol) for analytical method development and quality control.

The molecular framework of 5,2'-dihydroxy-6,7,8,6'-tetramethoxyflavone 5-hydroxy-2-(2-hydroxy-6-methoxy-phenyl)-6,7,8-trimethoxy-chromen-4-one 5-hydroxy-2-(2-hydroxy-6-methoxyphenyl)-6,7,8-trimethoxy-4H-1-benzopyran-4-one 55084-08-7 CHEBI:9061 neobaicalein scullcapflavone II skullcapflavone II (C19H18O8) 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 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.
