Used primarily as a chelating agent in analytical chemistry to form stable complexes with metal ions, enabling the detection and quantification of metals like iron, copper, and zinc in various samples. It is also employed in biochemical research to study enzyme inhibition and metal ion interactions in biological systems. Additionally, it finds application in the synthesis of coordination polymers and as a precursor in the development of luminescent materials for optical sensors. Its ability to bind selectively to specific metal ions makes it valuable in environmental monitoring for detecting metal contamination in water and soil.
