Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in Suzuki-Miyaura cross-coupling reactions to build complex aromatic frameworks. Its dual aldehyde and boronic acid functional groups allow for sequential transformations, enabling the construction of multifunctional molecules. Commonly employed in the development of fluorescent probes and sensors due to the reactivity of the formyl groups toward condensation reactions. Also finds use in materials science for designing covalent organic frameworks (COFs) where precise molecular geometry and reactivity are required.
