Used as a ligand in coordination chemistry, particularly in the formation of metal complexes for catalytic applications. Its structure allows strong chelation with transition metals, making it valuable in catalyzing oxidation reactions and promoting electron transfer processes. Commonly employed in research related to photoredox catalysis and artificial photosynthesis due to its ability to stabilize reactive metal centers and support light-induced electron transfer. Also utilized in the development of sensors and molecular devices where redox-active components are required.
