m-cresol púrpura

Descripción:

m-cresol púrpura, con el número CAS 2303-01-7, es un compuesto orgánico sintético comúnmente utilizado como indicador de pH en diversas aplicaciones químicas y biológicas. Es un miembro de la familia de compuestos fenólicos y se caracteriza por su capacidad para cambiar de color en respuesta a variaciones de pH, típicamente pasando de amarillo en condiciones ácidas a púrpura en entornos alcalinos. Esta propiedad lo hace particularmente útil en titulaciones y en el monitoreo de niveles de pH en entornos de laboratorio. m-cresol púrpura es soluble en agua y en disolventes orgánicos, lo que mejora su versatilidad en diferentes medios. Además, tiene un perfil de toxicidad relativamente bajo, lo que lo hace adecuado para su uso en sistemas biológicos. El compuesto se utiliza a menudo en la preparación de soluciones tampón y en el estudio de equilibrios ácido-base. Sus características estructurales incluyen un moiety de cresol, que contribuye a sus propiedades colorimétricas, y es importante manejarlo con cuidado, siguiendo las pautas de seguridad adecuadas, debido a su naturaleza química.

meta-Cresol Purple

CAS: 2303-01-7

Meta-Cresol Purple (MCP) is a fluorescent dye that is used to detect DNA polymerase chain reaction products. It is a cationic dye with an absorption maximum of 590 nm in the visible spectrum. MCP has been shown to bind to nucleic acids and therefore can be used as a probe for detecting DNA polymerase chain reaction products. The detection time for MCP can be up to 10 minutes. The biological studies show that MCP binds to the 3' hydroxyl group of the ribose sugar backbone of nucleic acids, which prevents the interaction of MCP with other biomolecules such as proteins. MCP has also been used in urine samples as an antimicrobial agent against bacterial strains like Escherichia coli and Pseudomonas aeruginosa and yeast strains like Candida albicans and Saccharomyces cerevisiae. MCP is soluble in sodium carbonate at neutral pH, but insoluble in water or
