Cefpirome Impurity 4 CAS CATO-C4X-12074

Description

Compared with other compounds in its class, the molecular weight of 530.58 g/mol gives Cefpirome Impurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Cefpirome Impurity 4 (CAS CATO-C4X-12074), a pharmacopoeial impurity reference standard (molecular formula C22H22N6O6S2, MW 530.58 g/mol) used for the identification and quantification of trace impurities in APIs.

Cefpirome Impurity 4 (C22H22N6O6S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Cefpirome Impurity 4 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.
