Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 423.40 g/mol gives Cefuroxime Sodium EP Impurity G distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Cefuroxime Sodium EP Impurity G (CAS 97232-98-9), a pharmacopoeial impurity reference standard (molecular formula C17H17N3O8S, MW 423.40 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Cefuroxime Sodium EP Impurity G (C17H17N3O8S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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 Cefuroxime Sodium EP Impurity G 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.
