This chemical is primarily used as a reagent in analytical chemistry for the detection and quantification of various metal ions, particularly iron and aluminum. It forms stable, colored complexes with these metals, making it useful in spectrophotometric analysis. Additionally, it serves as a chelating agent in industrial processes to control metal ion concentrations and prevent unwanted reactions. In the textile industry, it is employed as a dye intermediate, aiding in the synthesis of specific dyes and pigments. Its water-soluble nature and ability to bind metals also make it suitable for use in water treatment processes to remove heavy metal contaminants. Furthermore, it finds application in biochemical research as a stabilizer for enzymes and proteins, helping to maintain their activity under various conditions.
