Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Moxifloxacin Impurity 85.
CATO supplies Moxifloxacin Impurity 85 (CAS CATO-C4X-107485), a pharmacopoeial impurity reference standard (molecular formula C22H26FN3O4HCl, MW 451.92 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C22H26FN3O4HCl, Moxifloxacin Impurity 85 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 451.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 85 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.
