Chemical Structure
Description
The molecular framework of Moxifloxacin EP Impurity C HCl (C22H26FN3O4HCl) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Moxifloxacin EP Impurity C HCl (CAS 2252446-70-9) is a certified pharmaceutical impurity reference standard with the molecular formula C22H26FN3O4HCl and a molecular weight of 451.92 g/mol.
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), Moxifloxacin EP Impurity C HCl 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.
