This chemical is primarily used as a dye and chromogenic reagent in analytical chemistry. It is particularly effective in the spectrophotometric determination of metal ions, such as copper, nickel, and cobalt, due to its ability to form stable, colored complexes with these metals. The compound is also employed in biological staining techniques to enhance the visibility of specific cellular components under microscopic examination. Additionally, it finds application in the development of chemical sensors for detecting trace amounts of metal ions in environmental and industrial samples. Its high sensitivity and selectivity make it a valuable tool in both qualitative and quantitative analysis.
