Dacarbazine EP Impurity B; Dacarbazine Related Compound A; Temozolomide Aminoimidazole Impurity
Descripción
Temozolomida EP Impurity A (HCl Salt) | CAS 72-40-2 | también reportada como Dacarbazine EP Impurity B o Temozolomide Aminoimidazole Impurity | es una impureza estructural relevante en la síntesis y formulación de temozolomida. Presenta características químicas que complican la purificación | incluyendo mayor polaridad y susceptibilidad a hidrólisis | lo que requiere técnicas analíticas robustas como HPLC con detección UV | LC-MS y RMN para identificación y cuantificación. Su presencia puede afectar perfil de impurezas | estabilidad y cumplimiento de especificaciones regulatorias | por lo que es crítica la evaluación de rutas de formación | condiciones de reacción y desarrollo de límites de aceptación y métodos de eliminación durante control de calidad.
