Used primarily as a chelating agent in biochemical and analytical applications. It effectively binds metal ions such as calcium, magnesium, and heavy metals, making it valuable in controlling metal-catalyzed reactions and preventing metal-induced degradation in sensitive formulations. Commonly found in buffer solutions for enzymatic assays, cell culture media, and diagnostic reagents where metal ion interference must be minimized. Its structure allows for high selectivity and stability in physiological pH ranges, enhancing its utility in biological systems. Also employed in pharmaceutical formulations to improve stability and shelf life by sequestering trace metal contaminants.
