Description
As a certified reference material (CRM), Flumetasone Impurity 15 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.
Flumetasone Impurity 15 (CAS CATO-C4X-191015) is a certified pharmaceutical impurity reference standard with the molecular formula C22H28F2O5 and a molecular weight of 410.45 g/mol.
The molecular framework of Flumetasone Impurity 15 (C22H28F2O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. 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 quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
