This chemical is primarily utilized in analytical chemistry as a chromogenic reagent. It is particularly effective in the spectrophotometric determination of various metal ions, such as cobalt, nickel, and copper, due to its ability to form colored complexes with these metals. The compound's azo group acts as a chelating agent, enabling selective and sensitive detection of trace metal concentrations in environmental and industrial samples. Additionally, it is employed in research laboratories for studying metal-ligand interactions and developing new analytical methods for metal ion quantification. Its stability and distinct color changes upon binding with specific metals make it a valuable tool in both qualitative and quantitative analyses.
