Used primarily as a ligand in coordination chemistry, it forms stable complexes with various metal ions, enhancing catalytic activity in organic synthesis. It is applied in the development of catalysts for polymerization reactions, particularly in producing high-performance polymers. Additionally, it is utilized in the synthesis of pharmaceuticals, where its metal complexes serve as intermediates or active components. Its ability to chelate metals also makes it valuable in analytical chemistry for metal ion detection and separation processes.
