Levofloxacin Impurity 31 CAS CATO-C4X-137131

Description

Compared with other compounds in its class, the molecular weight of 333.28 g/mol gives Levofloxacin Impurity 31 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Levofloxacin Impurity 31 (CAS CATO-C4X-137131, C15H15F4NO3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Levofloxacin Impurity 31 (C15H15F4NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

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 31 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.
