Used in organic synthesis as a key intermediate for the preparation of various pharmaceuticals, particularly in the development of kinase inhibitors. 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 coupling with aryl or vinyl halides, making it valuable in drug discovery and medicinal chemistry. Additionally, it is employed in the synthesis of biologically active compounds targeting cancer and other diseases. Its structural versatility allows for modifications to enhance drug efficacy and selectivity.
