Chemical Structure
Description
Betamethasone β-D-Glucuronide (CAS 744161-79-3), molecular formula C28H37FO11 and molecular weight 568.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Betamethasone β-D-Glucuronide (C28H37FO11) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 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), Betamethasone β-D-Glucuronide 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.
