Arsenazo III is an azo derivative of chromotropic acid, a metal chrome dye, a chelating agent, and a cation complexing agent. Arsenazo III forms stable 1:1 complexes with Ca2+, Mg2+, Sr2+, Ba2+, K+, and Na+, and its binding affinity for Ca2+ depends on pH, alkali metal cation concentration, and buffer parameters. Arsenazo III serves as a colorimetric indicator for micromolar ionized Ca2+ in cells[1][2].
