This chemical is primarily used as a chelating agent in the synthesis of metal complexes, particularly in coordination chemistry. It is widely employed in the development of luminescent materials, where it acts as a ligand to enhance the photophysical properties of metal ions, such as ruthenium or iridium, in organic light-emitting diodes (OLEDs) and other optoelectronic devices. Additionally, it serves as a key component in the preparation of catalysts for organic transformations, including oxidation and polymerization reactions. Its ability to stabilize metal centers also makes it valuable in the study of electron transfer processes and in the design of sensors for detecting metal ions in analytical chemistry.
