This chemical is widely used as a chelating agent in coordination chemistry, particularly for forming stable complexes with metal ions like iron, copper, and zinc. Its applications include acting as a reagent in analytical chemistry for the spectrophotometric determination of metal concentrations. Additionally, it is utilized in the development of electrochemical sensors due to its ability to enhance electron transfer processes. In materials science, it serves as a building block for synthesizing metal-organic frameworks (MOFs) and other functional materials. It also finds use in biochemical research as a probe for studying metal ion interactions in biological systems.
