CAS 15905-32-5: 2′,4′,5′,7′-Tetraiodofluoresceína
Descripción:
2′,4′,5′,7′-Tetraiodofluoresceína, con el número CAS 15905-32-5, es un compuesto orgánico sintético que pertenece a la familia de la fluoresceína, caracterizado por su intensa fluorescencia. Este compuesto presenta un núcleo de xanteno con cuatro átomos de yodo sustituidos en las posiciones 2′, 4′, 5′ y 7′, lo que altera significativamente sus propiedades ópticas en comparación con los derivados de fluoresceína no yodados. La presencia de yodo mejora su lipofilia y puede afectar su solubilidad en varios disolventes. La tetraiodofluoresceína se utiliza principalmente como un colorante fluorescente en aplicaciones biológicas y químicas, incluyendo microscopía y citometría de flujo, debido a su alta eficiencia cuántica y estabilidad bajo exposición a la luz. Además, puede servir como un trazador en estudios ambientales y tiene aplicaciones potenciales en terapia fotodinámica. Su estructura química contribuye a sus propiedades espectrales únicas, haciéndola valiosa en campos de investigación y diagnóstico. Sin embargo, el manejo debe hacerse con cuidado, considerando la toxicidad potencial asociada con compuestos halogenados.

CAS:Erythrosin B is a fluorescent dye that is used in biological research. It has been shown to have cytotoxic effects on human leukemia cells (HL-60) and cytotoxic effects on human lymphocytes. The toxicities of this compound are dependent on the concentration and the duration of exposure, as well as the type of biological sample. Erythrosin B can be used to detect DNA damage in cells by using an analytical method called matrix effect synchronous fluorescence. This dye appears to be genotoxic in vitro and in vivo, but its long-term toxicity is unknown. Erythrosin B has antimicrobial properties against gram-positive bacteria and fungi, but it does not have any activity against Gram negative bacteria or viruses.Fórmula:C20H8I4O5Pureza:Min. 95%Forma y color:PowderPeso molecular:835.89 g/molSpiro[isobenzofuran-1(3H),9'-[9H]xanthen]-3-one, 3',6'-dihydroxy-2',4',5',7'-tetraiodo-
