Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in Suzuki-Miyaura cross-coupling reactions to construct biaryl frameworks. Its aldehyde and boronic acid functional groups allow for sequential transformations, enabling the development of complex organic molecules. Commonly employed in medicinal chemistry for building blocks in drug discovery, especially in kinase inhibitors and anti-inflammatory agents. Also utilized in the preparation of fluorescent probes and sensors due to the reactivity of the formyl group in condensation reactions.
