Descripción
El informe sobre N-Nitroso Chlorothiazide (N-nitrosoclorotiazida) documenta una impureza de tipo nitrosamina relevante para control de calidad farmacéutico. Se describe su perfil analítico, baja estabilidad y tendencia a fragmentarse, lo que complica la obtención de un estándar de referencia puro. Los intentos de síntesis resultaron en rendimientos inconsistentes y subproductos que interfieren en cromatografía y espectrometría de masas, impidiendo una caracterización inequívoca por NMR y LC-MS de alta resolución. Este reporte es esencial para laboratorios de aseguramiento de calidad que requieren estrategias de detección y cuantificación a niveles trazas, gestión de riesgos y cumplimiento regulatorio.
