Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-Methoxy-2,12-diphenyl-3,4-dihydrodipyrano[2,3-a:2',3',4'-kl]xanthen-9(2H)-one (CAS 35290-22-3), a certified reference material (molecular formula C31H22O5, MW 474.50 g/mol) for analytical method development and quality control.
The molecular framework of 5-Methoxy-2,12-diphenyl-3,4-dihydrodipyrano[2,3-a:2',3',4'-kl]xanthen-9(2H)-one (C31H22O5) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 5-Methoxy-2,12-diphenyl-3,4-dihydrodipyrano[2,3-a:2',3',4'-kl]xanthen-9(2H)-one 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.
