Compared with other compounds in its class, the molecular weight of 398.39 g/mol gives Mezlocillin Impurity 12 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Mezlocillin Impurity 12 (CAS CATO-C4X-183112) is a certified pharmaceutical impurity reference standard with the molecular formula C15H18N4O7S and a molecular weight of 398.39 g/mol.
Based on its molecular formula C15H18N4O7S, Mezlocillin Impurity 12 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 398.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Mezlocillin Impurity 12 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.
