Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 476.39 g/mol gives Diosmetin 3-O-β-D-Glucuronide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diosmetin 3-O-β-D-Glucuronide (CAS 152503-50-9), molecular formula C22H20O12 and molecular weight 476.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Diosmetin 3-O-β-D-Glucuronide (C22H20O12) 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.
CATO manufactures Diosmetin 3-O-β-D-Glucuronide 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.
