This chemical is primarily utilized in analytical chemistry as a sensitive reagent for the spectrophotometric determination of trace elements, particularly metals like aluminum, iron, and titanium. Its ability to form stable, colored complexes with these metals makes it valuable for quantitative analysis in environmental and industrial samples. Additionally, it is employed in research laboratories for studying metal ion interactions and developing new analytical methods. Its high selectivity and sensitivity contribute to its effectiveness in detecting low concentrations of metals in complex matrices.
