CAS 860-22-0: Indigo carmín
Descripción:
Indigo carmín, también conocido como ácido indigotindisulfonico, es un colorante sintético caracterizado por su color azul profundo. Se utiliza comúnmente en diversas aplicaciones, incluyendo como agente colorante alimentario (E132), en productos farmacéuticos y en tinciones biológicas. La fórmula química de Indigo carmín es C16H8N2Na2O8S2, lo que indica que contiene grupos de sodio y sulfonato, que mejoran su solubilidad en agua. Este compuesto exhibe una excelente estabilidad en condiciones normales, pero puede degradarse cuando se expone a ácidos o bases fuertes. Indigo carmín es conocido por su capacidad para absorber luz en el espectro visible, lo que lo hace útil en ensayos colorimétricos. Además, se ha utilizado en diagnósticos médicos, particularmente en procedimientos como pruebas de función renal. Los datos de seguridad indican que Indigo carmín se considera generalmente seguro para su uso en alimentos y productos farmacéuticos, aunque algunas personas pueden experimentar reacciones alérgicas. En general, su color vibrante y versatilidad hacen de Indigo carmín un compuesto valioso en diversos campos.
