Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 480.94 g/mol gives Empagliflozin Impurity 48 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Empagliflozin Impurity 48 (CAS 915095-96-4), a pharmacopoeial impurity reference standard (molecular formula C24H29ClO8, MW 480.94 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Empagliflozin Impurity 48 (C24H29ClO8) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, chlorine 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.
CATO manufactures Empagliflozin Impurity 48 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.
