Used in organic synthesis as a building block for pharmaceuticals and agrochemicals, particularly in the development of ligands for catalytic reactions. Its aldehyde functional group allows for easy modification through condensation or reduction reactions, making it valuable in the preparation of nitrogen-containing heterocyclic compounds. Commonly employed in the synthesis of metal-organic frameworks (MOFs) and coordination polymers due to its ability to chelate metal ions. Also finds use in the design of fluorescent sensors and optoelectronic materials owing to its conjugated structure and electron-donating properties.
