Sitafloxacin impurity 89 CAS CATO-C4X-115589

Description

Compared with other compounds in its class, the molecular weight of 365.71 g/mol gives Sitafloxacin impurity 89 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Sitafloxacin impurity 89 (CAS CATO-C4X-115589), a pharmacopoeial impurity reference standard (molecular formula C15H12ClF4NO3, MW 365.71 g/mol) used for the identification and quantification of trace impurities in APIs.

Sitafloxacin impurity 89 (C15H12ClF4NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.

CATO manufactures Sitafloxacin impurity 89 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.
