Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It plays a crucial role in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds to create complex molecules. Its boronic acid group facilitates the coupling with aryl halides, making it valuable in drug discovery and development. Additionally, it is employed in the synthesis of fluorescent probes and sensors due to its ability to interact with specific biological targets. Its formyl group allows for further functionalization, enhancing its versatility in designing advanced materials and bioactive compounds.
