Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 355.25 g/mol gives Cefepime Impurity C56 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cefepime Impurity C56 (CAS 113703-50-7) is a certified pharmaceutical impurity reference standard with the molecular formula C12H17N3O3SHClCl and a molecular weight of 355.25 g/mol.
Cefepime Impurity C56 (C12H17N3O3SHClCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Cefepime Impurity C56 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.
