La impureza 2-Bromo-2′-cloropropiofenona aparece frecuentemente como subproducto en reacciones de halogenación y puede afectar la calidad de lotes intermedios y finales; presenta señales características en espectros de RMN y masas que facilitan su identificación y cuantificación mediante HPLC | GC-MS y qNMR | y su presencia puede alterar el perfil de impurezas relacionadas y la estabilidad del material objetivo. Un control analítico riguroso es esencial para establecer límites de aceptación y para validar métodos de limpieza y separación | minimizando riesgos regulatorios y garantizando reproducibilidad en procesos de síntesis orgánica donde esta impureza pueda formarse.
