Descripción
Impureza E de Escitalopram (CAS 103146-26-5) | también conocida como Escitalopram Related Compound A o Citadiol Hydrobromide | es una impureza relacionada relevante en los procesos de síntesis y control de calidad del escitalopram. Su perfil fisicoquímico incluye alta polaridad y potencial de formación durante etapas de bromación o salificación | lo que exige métodos analíticos específicos como LC-MS y HPLC con detección UV para su identificación y cuantificación. La caracterización estructural y el estudio de estabilidad permiten establecer límites de aceptación y procedimientos de eliminación eficaces. El control de esta impureza es crítico para cumplir requisitos regulatorios y garantizar la pureza del lote.
