CAS 7365-45-9: Ácido 4-(2-hidroxietil)-1-piperazinaetanosulfônico

Descrição: Ácido 4-(2-hidroxietil)-1-piperazinaetanosulfônico, comumente conhecido como HEPES, é um agente tampão zwitteriônico amplamente utilizado em pesquisas biológicas e bioquímicas. Tem um valor de pKa em torno de 7,5, tornando-o particularmente eficaz para manter o pH fisiológico em culturas celulares e ensaios bioquímicos. HEPES é solúvel em água e exibe boa estabilidade em condições fisiológicas, o que é crucial para experimentos que requerem níveis de pH consistentes. Sua estrutura apresenta um anel de piperazina, um grupo ácido sulfônico e uma cadeia lateral de hidroxietila, que contribuem para sua capacidade de tamponamento. HEPES é não tóxico para as células, tornando-o adequado para várias aplicações, incluindo purificação de proteínas e ensaios enzimáticos. Além disso, é menos propenso a interferir com processos biológicos em comparação com outros tampões, como os tampões fosfato. No entanto, é importante notar que o HEPES pode absorver luz UV, o que pode afetar certas análises espectroscópicas. No geral, o HEPES é um tampão versátil e amplamente utilizado em ambientes de laboratório, particularmente nos campos da biologia molecular e bioquímica.
