Description
CATO supplies Moxifloxacin Impurity 19 (CAS 2445515-66-0(Free Base)), a pharmacopoeial impurity reference standard (molecular formula C21H25N3O5HCl, MW 435.90 g/mol) used for the identification and quantification of trace impurities in APIs.
Moxifloxacin Impurity 19 (C21H25N3O5HCl) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures Moxifloxacin Impurity 19 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
