Used as a key intermediate in the synthesis of complex organic molecules, particularly in pharmaceuticals and fine chemicals. Its aldehyde and ether functional groups allow for selective reactions, making it valuable in constructing multi-step organic frameworks. Commonly employed in the development of fluorescent dyes and sensors due to its aromatic structure and reactivity. Also utilized in the preparation of ligands for catalytic metal complexes and in the formation of heterocyclic compounds through cyclization reactions.
