Used as a ligand in coordination chemistry, particularly in the formation of metal complexes for catalytic applications. Its structure allows chelation with transition metals, making it valuable in catalyzing organic transformations such as cross-coupling reactions and C–H activation. Also employed in the development of photoredox catalysts due to its ability to stabilize metal centers in specific oxidation states. Additionally, it serves as a building block in synthesizing functional materials for use in sensors and molecular electronics.
