Used extensively in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, to create biaryl compounds. It serves as a key intermediate in the production of pharmaceuticals, agrochemicals, and functional materials. Its boronic acid group enables efficient conjugation with diols, making it valuable in carbohydrate chemistry and sensor development. Additionally, it is employed in the preparation of boron-containing polymers and as a ligand in catalysis. Its hydrochloride form enhances solubility, facilitating its use in aqueous reaction environments.
