4-(1-methoxy-2-(methylamino)ethyl)benzene-1 | 2-diol (CAS 06/02/2947) es una impureza polar derivada de reacciones de metilación y aminación que presenta un núcleo catecol susceptible a oxidación y formación de subproductos coloreados. En controles de calidad su perfil analítico se define por retención temprana en HPLC reversa | señal distintiva en LC-MS y resonancias características en NMR. Su alta afinidad por iones metálicos y solubilidad en solventes polares requieren condiciones de purificación específicas y estabilizantes antioxidantes. Se recomienda monitorizar niveles por HPLC-UV/LC-MS y cuantificar por qNMR para asegurar cumplimiento de límites de impurezas y estabilidad durante almacenamiento.
