Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct biaryl frameworks found in pharmaceuticals and agrochemicals. Its aldehyde and boronic acid functional groups allow sequential transformations, enabling the synthesis of complex molecules. Commonly employed in the development of drug candidates, especially in medicinal chemistry for building aromatic structures with specific substitution patterns. Also utilized in the preparation of fluorescent probes and sensors due to the reactivity of the formyl group in condensation reactions.
