CAS 76-54-0: 2′,7′-Diclorofluoresceína
Descripción:
2′,7′-Diclorofluoresceína, con el número CAS 76-54-0, es un compuesto orgánico sintético ampliamente utilizado como colorante fluorescente e indicador de pH. Exhibe una fluorescencia verde brillante cuando se excita con luz ultravioleta o azul, lo que lo hace valioso en diversas aplicaciones biológicas y químicas, incluyendo microscopía y citometría de flujo. El compuesto tiene una fórmula molecular de C13H8Cl2O5 y presenta dos átomos de cloro sustituidos en las posiciones 2' y 7' de la estructura de la fluoresceína, lo que mejora su fotostabilidad y solubilidad en soluciones acuosas. 2′,7′-Diclorofluoresceína es sensible a los cambios de pH, mostrando variaciones distintas en la intensidad de fluorescencia a través de diferentes niveles de pH, lo que permite su uso en el monitoreo de entornos celulares. Además, es no tóxico a bajas concentraciones, lo que lo hace adecuado para estudios biológicos. Sin embargo, al igual que muchas sustancias químicas, debe manejarse con cuidado, siguiendo los protocolos de seguridad apropiados para evitar la exposición.
