Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 417.43 g/mol gives Moxifloxacin impurity 182 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Moxifloxacin impurity 182 (CAS CATO-C4X-1074182) is a certified pharmaceutical impurity reference standard with the molecular formula C21H24FN3O5 and a molecular weight of 417.43 g/mol.
Moxifloxacin impurity 182 (C21H24FN3O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. 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), Moxifloxacin impurity 182 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.
