Compared with other compounds in its class, the molecular weight of 291.14 g/mol gives Ozenoxacin Impurity 66 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ozenoxacin Impurity 66 (CAS 23612-56-8) is a certified pharmaceutical impurity reference standard with the molecular formula C13H11BrN2O and a molecular weight of 291.14 g/mol.
The molecular framework of Ozenoxacin Impurity 66 (C13H11BrN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), Ozenoxacin Impurity 66 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
