Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules and heterocyclic compounds. Its dual aldehyde functionality allows for selective reactions, making it valuable in constructing complex organic frameworks. Commonly employed in the preparation of fluorescent dyes and sensors due to its ability to form conjugated systems. Also utilized in coordination chemistry as a ligand precursor for metal-organic frameworks (MOFs) and catalysts. Its bromine substituent enables further functionalization via cross-coupling reactions, expanding its utility in medicinal chemistry and materials science.
