Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its boronic acid functionality enables participation in Suzuki-Miyaura cross-coupling reactions, making it valuable in constructing carbon-carbon bonds during drug discovery. The aldehyde and benzyl-protected hydroxyl groups allow for further selective modifications, facilitating the creation of complex organic structures. Commonly employed in medicinal chemistry for building blocks in targeted therapies, especially in oncology and inflammation research.
