Widely used as a chelating agent in coordination chemistry, it forms stable complexes with various metal ions, making it valuable in catalysis and metal ion separation processes. It serves as a crosslinking agent in the synthesis of polymers and resins, enhancing their mechanical and thermal properties. In biochemistry, it is utilized as a buffer component and in the modification of proteins and nucleic acids. Additionally, it acts as a precursor in the production of dendrimers and other nanostructured materials, which have applications in drug delivery and nanotechnology. Its versatility also extends to organic synthesis, where it is employed as a building block for creating complex molecules.
