CAS 25561-30-2: bis(trimetilsilil)trifluoroacetamida

Descripción: bis(trimetilsilil)trifluoroacetamida (CAS 25561-30-2) es un compuesto químico comúnmente utilizado como agente derivatizante en química analítica, particularmente en cromatografía de gases y espectrometría de masas. Presenta un grupo funcional trifluoroacetamida, que mejora la volatilidad y la estabilidad térmica de los analitos, facilitando su análisis. El compuesto se caracteriza por su alta reactividad debido a la presencia del grupo trifluoroacetamida, que puede formar derivados estables con varios grupos funcionales, incluidos alcoholes y aminas. Su estructura incluye dos grupos trimetilsililo, que contribuyen a su capacidad para proteger grupos funcionales sensibles durante el análisis. bis(trimetilsilil)trifluoroacetamida es típicamente un líquido incoloro a amarillo pálido con un olor distintivo. Es soluble en disolventes orgánicos y generalmente es estable en condiciones de laboratorio estándar. Sin embargo, debe manejarse con cuidado debido a su potencial para liberar gases tóxicos al descomponerse. Se recomiendan medidas de seguridad adecuadas, incluido el uso de equipo de protección personal, al trabajar con este compuesto.
