Cefathiamidine Impurity 22 CAS CATO-C4X-133722

Description

Compared with other compounds in its class, the molecular weight of 373.47 g/mol gives Cefathiamidine Impurity 22 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Cefathiamidine Impurity 22 (CAS CATO-C4X-133722), a pharmacopoeial impurity reference standard (molecular formula C10H12N2O5SC6H15N, MW 373.47 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Cefathiamidine Impurity 22 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 373.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Cefathiamidine Impurity 22 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.
