5,7,3',4'-Tetra-O-benzylepicatechin (CAS 87292-49-7) is a high-purity analytical reference standard with the molecular formula C43H38O6 and a molecular weight of 650.76 g/mol.
The molecular framework of 5,7,3',4'-Tetra-O-benzylepicatechin (C43H38O6) 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).
CATO manufactures 5,7,3',4'-Tetra-O-benzylepicatechin 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.
