Used as a chelating agent in analytical chemistry to detect and quantify metal ions, particularly in complexometric titrations. It forms stable complexes with metals, aiding in their separation and identification. In industrial applications, it serves as a cross-linking agent in polymer production, enhancing the durability and stability of materials. Additionally, it is employed in the synthesis of dyes and pigments, contributing to the vibrancy and colorfastness of textile products. Its role in organic synthesis includes acting as an intermediate for producing various chemical compounds, particularly in pharmaceuticals and agrochemicals.
