Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 250.04 g/mol gives Nadifloxacin Impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Nadifloxacin Impurity 15 (CAS 64695-81-4) is a certified pharmaceutical impurity reference standard with the molecular formula C8H6BrF2NO and a molecular weight of 250.04 g/mol.
The molecular framework of Nadifloxacin Impurity 15 (C8H6BrF2NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Nadifloxacin Impurity 15 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.
