: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.

CAS:Indigo carmine (Standard) is the standard for Indigo carmine (T19755). Indigo carmine (Fd&c blue no. 2) is a synthetic blue food colorant; in addition to being a dye, it can directly serve as a model substrate in visible-light photocatalytic degradation research, used to evaluate the degradation performance of photocatalytic systems such as TiO₂, CeO₂, and g-C₃N₄ toward organic dyes. In bacteriophage research, Indigo carmine shows selective inactivation against DNA phages P001, T4, T1, T7, and λ, with EC₅₀ of 0.006-0.105 mg/mL, while no obvious activity was observed against RNA phage MS2. Indigo carmine can selectively bind double-stranded DNA and promote phage genome release and capsid deformation, and under specific experimental conditions can reduce phage titers by up to approximately 7-log. Indigo carmine can therefore be used in research on photocatalytic dye degradation, phage inactivation, and DNA interactions.Fórmula:C16H8N2Na2O8S2Peso molecular:466.35Indigotine 100 µg/mL in Acetonitrile:Water
