Chemical Structure

Ozefloxacin Impurity 18 CAS 856836-09-4 chemical structure

Description

CATO supplies Ozefloxacin Impurity 18 (CAS 856836-09-4), a pharmacopoeial impurity reference standard (molecular formula C14H14N2O, MW 226.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C14H14N2O, Ozefloxacin Impurity 18 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 226.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Ozefloxacin Impurity 18 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.
