Description
CATO supplies 2-(3-((2R,3S)-5,7-Dihydroxy-2-(4-hydroxyphenyl)-4-oxochroman-3-yl)-4-hydroxyphenyl)-5,7-dihydroxy-4H-chromen-4-one (CAS 159194-98-6), a certified reference material (molecular formula C30H20O10, MW 540.47 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-((2R,3S)-5,7-Dihydroxy-2-(4-hydroxyphenyl)-4-oxochroman-3-yl)-4-hydroxyphenyl)-5,7-dihydroxy-4H-chromen-4-one (C30H20O10) 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.
As a certified reference material (CRM), 2-(3-((2R,3S)-5,7-Dihydroxy-2-(4-hydroxyphenyl)-4-oxochroman-3-yl)-4-hydroxyphenyl)-5,7-dihydroxy-4H-chromen-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.
