Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 307.27 g/mol gives Levofloxacin impurity 69 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Levofloxacin impurity 69 (CAS CATO-C4X-137169) is a certified pharmaceutical impurity reference standard with the molecular formula C15H14FNO5 and a molecular weight of 307.27 g/mol.
Levofloxacin impurity 69 (C15H14FNO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Levofloxacin impurity 69 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.
