Arsenazo III

Descrizione:

Arsenazo III, con il numero CAS 1668-00-4, è un composto organico sintetico utilizzato principalmente come agente chelante e reagente colorimetrico in chimica analitica. È particolarmente efficace per la rilevazione e la quantificazione di ioni metallici, specialmente quelli dei metalli di transizione, grazie alla sua capacità di formare complessi stabili. Il composto mostra un cambiamento di colore distintivo al legarsi con ioni metallici specifici, rendendolo utile in varie applicazioni analitiche, inclusa la spettrofotometria. Arsenazo III è caratterizzato dalla sua struttura di colorante azoico, che contribuisce alle sue proprietà cromogeniche. È solubile in acqua e mostra stabilità in un intervallo di condizioni di pH, sebbene le sue prestazioni possano essere influenzate dalla presenza di ioni concorrenti. Le considerazioni di sicurezza sono importanti quando si maneggia Arsenazo III, poiché contiene arsenico, che è tossico e presenta rischi per la salute. Devono essere seguiti protocolli di laboratorio adeguati per mitigare l'esposizione. In generale, Arsenazo III è uno strumento prezioso nella chimica analitica per la rilevazione e la quantificazione di ioni metallici.

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.
