Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 594.58 g/mol gives Cefepime Impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cefepime Impurity 15 (CAS CATO-C4X-119315) is a certified pharmaceutical impurity reference standard with the molecular formula C19H25N6O5S2C2F3O2 and a molecular weight of 594.58 g/mol.
Based on its molecular formula C19H25N6O5S2C2F3O2, Cefepime Impurity 15 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 594.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Cefepime Impurity 15 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.
