CAS 547-58-0: Alaranjado de metilo
Descrição:
Alaranjado de metilo é um corante azoico comumente usado como indicador de pH em titulações, particularmente na faixa ácida. Sua fórmula química é C14H14N3NaO3S, e aparece como um pó amarelo a vermelho, dependendo do pH da solução. Alaranjado de metilo exibe uma mudança de cor distinta de vermelho em um pH abaixo de 3,1 para amarelo em um pH acima de 4,4, tornando-o útil para determinar o ponto final de reações ácido-base. É solúvel em água e tem uma toxicidade relativamente baixa, embora ainda deva ser manuseado com cuidado. O composto é estável em condições normais, mas pode se degradar quando exposto a agentes oxidantes fortes ou níveis extremos de pH. Alaranjado de metilo também é utilizado em várias aplicações além da indicação de pH, incluindo em processos de tingimento e como uma coloração biológica. Suas propriedades únicas o tornam uma ferramenta valiosa tanto em ambientes laboratoriais quanto industriais.

CAS:Methyl orange is a dye that is used as an indicator in acid-base titrations. It has a basic structure and can be prepared by the oxidation of para-aminobenzoic acid with hydrogen peroxide. Methyl orange has been shown to exhibit synergistic effects with other antimicrobial agents, such as phenol, methylene blue, and chlorhexidine at pH levels of 4.5 to 7.0. The optimum concentration for the matrix effect is 0.01% at pH range from 2.5 to 4.5 and 1% at pH range from 5 to 7.5. Methyl orange is activated by light with wavelengths between 300 nm and 500 nm and can be used in wastewater treatment processes where there are high levels of organic matter or radiation, such as carthamus tinctorius or zirconium oxide.Fórmula:C14H15N3O3S•NaPureza:Min. 95%Cor e Forma:PowderPeso molecular:328.34 g/molMethyl orange, Indicator
