Used as a key building block in coordination chemistry, particularly in the synthesis of metal-organic frameworks (MOFs) and supramolecular architectures. Its ability to act as a bridging ligand allows the formation of extended structures with transition metals, useful in catalysis and materials science. Employed in the development of electroactive materials and sensors due to its redox-active nature. Found in the design of dye-sensitized solar cells (DSSCs) and other photovoltaic devices as a component for electron transfer systems. Also applied in the preparation of ionic liquids and as a precursor for herbicides, though its primary value lies in research and advanced material development.
