Verde de bromocresol

Descripción:
Verde de bromocresol es un colorante sintético e indicador de pH comúnmente utilizado en diversas aplicaciones bioquímicas. Se caracteriza por su capacidad para cambiar de color en respuesta a variaciones de pH, típicamente pasando de amarillo en condiciones ácidas a azul en entornos alcalinos, con un rango de transición de pH alrededor de 3.8 a 5.4. Esta propiedad lo hace valioso en titulaciones y como un tinte biológico. Químicamente, Verde de bromocresol es un derivado de fenol sulfonado, y su estructura molecular incluye átomos de bromo, que contribuyen a sus propiedades colorimétricas. Es soluble en agua y exhibe un espectro de absorción distinto, lo que lo hace útil en análisis espectrofotométricos. Además, Verde de bromocresol se emplea a menudo en laboratorios microbiológicos y clínicos para la detección de ciertos microorganismos y en la evaluación de concentraciones de proteínas. Aunque generalmente se considera seguro para su uso en laboratorio, es importante manejarlo con cuidado, como con todas las sustancias químicas, para evitar posibles riesgos para la salud.

  • Bromocresol green

    CAS:

    Bromocresol green is a cationic surfactant that is used as a fluorescent indicator dye. It binds to proteins and can be detected with an optical sensor. Bromocresol green has been shown to react with hydrochloric acid, which may be due to the protonation of the cationic group. This reaction is reversible and depends on pH. The binding of bromocresol green to serum proteins results in a decrease in fluorescence intensity due to quenching by adsorption at the protein-protein interface. The kinetic data for this dye have been found to depend on α1-acid glycoprotein concentration.
