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 41(R,S).
Moxifloxacin Impurity 41(R,S) (CAS 855661-71-1) is a certified pharmaceutical impurity reference standard with the molecular formula C21H24FN3O4 and a molecular weight of 401.43 g/mol.
The molecular framework of Moxifloxacin Impurity 41(R,S) (C21H24FN3O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. 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 41(R,S) 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.
