Product Information

• Product Number: N031173

• English Name: N-Nitroso Ozenoxacin

• English Alias: 1-cyclopropyl-8-methyl-7-(5-methyl-6-(methyl(nitroso)amino)pyridin-3-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid

• CAS Number: None

• Molecular Formula: C₂₁H₂₀N₄O₄

• Molecular Weight: 392.41

Advantages

• Well-defined and distinct structure: Contains nitroso (-N=O) group, quinolinone ring, cyclopropyl, and pyridinyl, differing from Ozenoxacin by methyl(nitroso)amino substitution on pyridine ring. It can be accurately identified by techniques such as HPLC and LC-MS, providing a specific marker for impurity detection;

• High stability and traceability: The N-nitrosamine structure is stable under acidic conditions. As a product of amino oxidation during Ozenoxacin storage or degradation, it directly reflects oxidative deterioration, improving quality tracing accuracy;

• High detection sensitivity: The conjugated system of quinolinone and nitroso groups shows strong UV absorption (270-290nm), and combined with carboxyl polarity, trace analysis can be achieved via HPLC-UV or LC-MS, compatible with quinolone detection systems.

Applications

• Pharmaceutical quality control: Used as an impurity reference to identify and quantify N-Nitroso Ozenoxacin in Ozenoxacin APIs and formulations, ensuring residual nitroso impurities meet quality standards;

• Stability evaluation: Assessing oxidative degradation trends of Ozenoxacin formulations under varying storage conditions (temperature, humidity) by monitoring impurity levels to support shelf-life determination;

• Degradation mechanism studies: Exploring oxidative breakdown pathways of Ozenoxacin, clarifying nitroso impurity formation conditions to optimize antioxidant production processes.

Background Description

Research Status

• Detection optimization: Using UPLC-MS/MS with quinolinone fragment monitoring to achieve ultra-trace detection (ppb level);

• Oxidation studies: Investigating impurity formation kinetics under different pH and light conditions to identify key factors driving amino oxidation in Ozenoxacin;

• Toxicological assessment: Evaluating genotoxic potential via in vitro tests to establish strict impurity limits;

• Stabilization strategies: Developing light-protective packaging and antioxidant formulations to minimize nitroso impurity formation in Ozenoxacin products.
