Chemical Structure
Description
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 supplies Ozenoxacin Impurity 75 (CAS CATO-C4X-279675), a pharmacopoeial impurity reference standard (molecular formula C21H21N3O4, MW 379.41 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Ozenoxacin Impurity 75 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 379.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures Ozenoxacin Impurity 75 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.
