CAS 76-60-8: Verde de bromocresol
Descrição:
Verde de bromocresol é um corante sintético e indicador de pH comumente utilizado em várias aplicações bioquímicas. É caracterizado por sua capacidade de mudar de cor em resposta a variações de pH, geralmente transitando de amarelo em condições ácidas para azul em ambientes alcalinos, com uma faixa de transição de pH em torno de 3,8 a 5,4. Essa propriedade o torna valioso em titulações e como uma coloração biológica. Quimicamente, Verde de bromocresol é um derivado de fenol sulfonado, e sua estrutura molecular inclui átomos de bromo, que contribuem para suas propriedades colorimétricas. É solúvel em água e exibe um espectro de absorção distinto, tornando-o útil em análises espectrofotométricas. Além disso, Verde de bromocresol é frequentemente empregado em laboratórios microbiológicos e clínicos para a detecção de certos microrganismos e na avaliação de concentrações de proteínas. Embora geralmente seja considerado seguro para uso em laboratório, é importante manuseá-lo com cuidado, como todas as substâncias químicas, para evitar potenciais riscos à saúde.

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.Fórmula:C21H14Br4O5SCor e Forma:PowderPeso molecular:698.01 g/mol
