(3R | 4R)-1-Nitroso Tofacitinib | también denominado Tofacitinib Nitrosamine 2 | es una impureza nitrosamina estereoquímica derivada del proceso de síntesis y degradación de tofacitinib. Presenta riesgo genotóxico potencial que requiere evaluación rigurosa y control en materias primas y lotes intermedios. Su detección y cuantificación se realiza típicamente por LC-MS/MS o HPLC con detectores específicos y métodos validados | incluyendo límites de cuantificación y recuperación. La comprensión de rutas de formación | condiciones de almacenamiento y precursores quimio selectivos es esencial para establecer especificaciones | estrategias de muestreo y procedimientos de mitigación. Se recomiendan patrones de referencia | estudios de estabilidad forzada y planes de evaluación analítica para garantizar cumplimiento regulatorio.
