CAS 7365-45-9: Ácido 4-(2-hidroxietil)-1-piperazinaetanosulfónico

Descripción: Ácido 4-(2-hidroxietil)-1-piperazinaetanosulfónico, comúnmente conocido como HEPES, es un agente amortiguador zwitteriónico ampliamente utilizado en la investigación biológica y bioquímica. Tiene un valor de pKa alrededor de 7.5, lo que lo hace particularmente efectivo para mantener el pH fisiológico en cultivos celulares y ensayos bioquímicos. HEPES es soluble en agua y exhibe buena estabilidad bajo condiciones fisiológicas, lo cual es crucial para experimentos que requieren niveles de pH consistentes. Su estructura presenta un anillo de piperazina, un grupo ácido sulfónico y una cadena lateral de hidroxietilo, que contribuyen a su capacidad de amortiguación. HEPES es no tóxico para las células, lo que lo hace adecuado para diversas aplicaciones, incluyendo la purificación de proteínas y ensayos enzimáticos. Además, es menos propenso a interferir con procesos biológicos en comparación con otros amortiguadores, como los amortiguadores de fosfato. Sin embargo, es importante señalar que HEPES puede absorber luz UV, lo que puede afectar ciertos análisis espectroscópicos. En general, HEPES es un amortiguador versátil y ampliamente utilizado en entornos de laboratorio, particularmente en los campos de la biología molecular y la bioquímica.
