N-Nitrosonorfloxacino (CAS 74011-53-3) es el derivado N-nitrosamina de norfloxacino y se clasifica químicamente como una impureza potencialmente genotóxica, originada por nitrosación de la función amina secundaria bajo condiciones de fabricación ácidas u oxidativas. Su fórmula molecular es C16H17FN4O4 y su masa molecular es de 348,33 g/mol. En el contexto regulatorio, esta clase se evalúa con especial rigor bajo ICH M7 debido a su posible reactividad con el ADN. Su determinación a nivel traza suele requerir LC-MS/MS de alta selectividad, a menudo complementada con espectrometría de masas de alta resolución, y en ciertos casos GC-MS tras derivatización o enriquecimiento. La confirmación estructural depende del análisis de fragmentos e isotopía.
