Arsenazo III

Descrição:

Arsenazo III, com o número CAS 1668-00-4, é um composto orgânico sintético utilizado principalmente como agente quelante e reagente colorimétrico em química analítica. É particularmente eficaz para a detecção e quantificação de íons metálicos, especialmente os de metais de transição, devido à sua capacidade de formar complexos estáveis. O composto exibe uma mudança de cor distinta ao se ligar a íons metálicos específicos, tornando-o útil em várias aplicações analíticas, incluindo espectrofotometria. Arsenazo III é caracterizado por sua estrutura de corante azoico, que contribui para suas propriedades cromogênicas. É solúvel em água e exibe estabilidade em uma variedade de condições de pH, embora seu desempenho possa ser influenciado pela presença de íons competidores. Considerações de segurança são importantes ao manusear Arsenazo III, pois contém arsênio, que é tóxico e apresenta riscos à saúde. Protocolos laboratoriais adequados devem ser seguidos para mitigar a exposição. No geral, Arsenazo III é uma ferramenta valiosa na química analítica para detecção e quantificação de íons metálicos.

Arsenazo III

CAS: 1668-00-4

Arsenazo III is a metal-binding dye that has been shown to bind to the cytosolic calcium ion. The binding of Arsenazo III to calcium has been shown to inhibit the voltage-dependent calcium channels, leading to a decrease in cytosolic calcium concentration. This reduction in cytosolic calcium is associated with energy metabolism and human serum titration calorimetry experiments. The binding of Arsenazo III to calcium is also responsible for its light signal. Arsenazo III binds to copper chloride and forms an insoluble precipitate when reacted with acidic solutions. This reaction can be used for analytical purposes as it produces a quantifiable end-point with plasma mass spectrometry.
