Rojo de Cresol

Descripción:

Rojo de Cresol es un compuesto orgánico comúnmente utilizado como indicador de pH en diversas aplicaciones químicas. Es un miembro de la familia de los fenoles y se caracteriza por su capacidad para cambiar de color dependiendo del pH de la solución en la que se encuentra, normalmente pasando de amarillo en condiciones ácidas a rojo en ambientes más alcalinos. El compuesto es soluble en agua y en disolventes orgánicos, lo que lo hace versátil para su uso en laboratorios. Rojo de Cresol tiene una fórmula molecular que refleja su estructura, que incluye un grupo fenólico y un grupo ácido sulfónico, contribuyendo a sus propiedades ácidas. A menudo se utiliza en investigaciones biológicas y químicas para monitorear los cambios de pH en experimentos, así como en diversas aplicaciones industriales. Se deben tener en cuenta consideraciones de seguridad, ya que Rojo de Cresol puede ser perjudicial si se ingiere o inhala, y se deben seguir los procedimientos de manejo apropiados. En general, Rojo de Cresol es una herramienta valiosa en la química analítica por sus propiedades confiables como indicador de pH.

Cresol red

CAS: 1733-12-6

Cresol red is a weak diacidic molecule and an anionic dye largely used in genetic and biochemical studies. Cresol red is commonly used to measure the pH of aqueous solutions also from environmental samples, e.g. seawater (Byrne, 1989). Cresol red shows an increased protonation in acidic water-based solutions at low temperatures (Heger, 2006). Cresol red can be used to introduce pH-sensing features to sensing materials, such as, optical fibres or nanoparticles (Islam, 2021).
