Impureza 2-aminobutanenitrile hidrocloruro (CAS 93554-80-4) aparece como sal cristalina del intermedio amino-nitrilo; su presencia en materiales farmacéuticos puede alterar el rendimiento de la síntesis y el perfil de impurezas del producto final. Tiene solubilidad en agua y solventes polares | estabilidad reducida frente a humedad y temperatura | y tendencia a oxidarse o dimerizar durante el almacenamiento. La identificación y cuantificación requieren HPLC con detección UV y LC-MS para especificidad | complementadas por RMN para confirmación estructural. Se recomienda establecer límites específicos | validar métodos analíticos y aplicar procedimientos de eliminación y control para minimizar riesgos de calidad y seguridad.
