:Rojo Congo
Descripción:
Rojo Congo es un colorante sintético que pertenece a la familia de los colorantes azoicos, caracterizado por su vibrante color rojo. Su fórmula química es C32H22N6Na2O6S2, y se conoce por su capacidad para unirse a proteínas, lo que lo hace útil en diversas aplicaciones biológicas. Rojo Congo exhibe una propiedad única de cambiar de color dependiendo del pH de la solución, apareciendo rojo en condiciones ácidas y azul en entornos alcalinos, un fenómeno conocido como indicador de pH. Se utiliza comúnmente en histología para teñir depósitos de amiloide en tejidos, ayudando en el diagnóstico de enfermedades como el Alzheimer. Además, Rojo Congo se ha empleado en la tintura textil y como un colorante biológico. Sin embargo, es importante señalar que Rojo Congo ha sido asociado con riesgos potenciales para la salud, incluyendo toxicidad y carcinogenicidad, lo que ha llevado a un escrutinio regulatorio en algunas aplicaciones. Se deben tomar las medidas de seguridad adecuadas al manejar este compuesto en entornos de laboratorio o industriales.

CAS:<p>Direct Red 28 is a dye that can be used in wastewater treatment. It can be adsorbed onto activated sludge, which reduces the amount of sludge needing to be treated. Direct Red 28 reacts with hydrogen peroxide to form a fluorescent derivative that has antimicrobial properties. Direct Red 28 also has been shown to have an effect on the enzyme activities of kidney bean extract and to inhibit the growth of bacteria in model systems. This dye is not toxic for body formation. However, it can react with potassium dichromate and hl-60 cells, which may lead to side effects such as skin irritation.</p>Fórmula:C32H24N6O6S2·2NaPureza:Min. 95%Forma y color:Red PowderPeso molecular:698.68 g/molCongo Red ACS, 75%
