Used in organic synthesis as a versatile building block for creating complex molecules, particularly in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds. It is also employed in the preparation of pharmaceutical intermediates and bioactive compounds. Additionally, it serves as a key reagent in the development of sensors and diagnostic tools due to its ability to interact with diols and sugars, making it useful in glucose monitoring and other biochemical applications. Its boronic acid group enables it to act as a ligand in catalysis and material science, contributing to the design of advanced polymers and nanomaterials.
