CATO supplies 4H-1-BEnzopyran-4-one, 3-[[6-O-(6-deoxy-alpha-L-mannopyranosyl)-beta-D-glucopyranosyl]oxy]-7-(beta-D-glucopyranosyloxy)-5-hydroxy-2-(4-hydroxy-3-methoxyphenyl)- (CAS 55481-91-9), a certified reference material (molecular formula C34H42O21, MW 786.68 g/mol) for analytical method development and quality control.
The molecular framework of 4H-1-BEnzopyran-4-one, 3-[[6-O-(6-deoxy-alpha-L-mannopyranosyl)-beta-D-glucopyranosyl]oxy]-7-(beta-D-glucopyranosyloxy)-5-hydroxy-2-(4-hydroxy-3-methoxyphenyl)- (C34H42O21) 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).
As a certified reference material (CRM), 4H-1-BEnzopyran-4-one, 3-[[6-O-(6-deoxy-alpha-L-mannopyranosyl)-beta-D-glucopyranosyl]oxy]-7-(beta-D-glucopyranosyloxy)-5-hydroxy-2-(4-hydroxy-3-methoxyphenyl)- 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.
