m-cresol púrpura

Descrição:

m-cresol púrpura, com o número CAS 2303-01-7, é um composto orgânico sintético comumente utilizado como indicador de pH em várias aplicações químicas e biológicas. É um membro da família de compostos fenólicos e é caracterizado por sua capacidade de mudar de cor em resposta a variações de pH, geralmente passando de amarelo em condições ácidas para roxo em ambientes alcalinos. Essa propriedade o torna particularmente útil em titulações e no monitoramento dos níveis de pH em ambientes de laboratório. m-cresol púrpura é solúvel em água e solventes orgânicos, o que aumenta sua versatilidade em diferentes meios. Além disso, possui um perfil de toxicidade relativamente baixo, tornando-o adequado para uso em sistemas biológicos. O composto é frequentemente utilizado na preparação de soluções tampão e no estudo de equilíbrios ácido-base. Suas características estruturais incluem um grupo cresol, que contribui para suas propriedades colorimétricas, e é importante manuseá-lo com cuidado, seguindo as diretrizes de segurança apropriadas, devido à sua natureza 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
