Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds for constructing biaryl compounds. Commonly applied in pharmaceutical research and development for synthesizing drug candidates and bioactive molecules. Also serves as a building block in materials science for developing fluorescent sensors and functional polymers. Its boronic acid group allows for reversible interactions with diols, making it useful in carbohydrate recognition and sensing applications.
