Used in organic synthesis as a building block for creating more complex molecules, particularly in cross-coupling reactions like Suzuki-Miyaura coupling. It serves as a key reagent in the production of pharmaceuticals, agrochemicals, and advanced materials. Its boronic acid group enables it to form stable bonds with other organic compounds, making it valuable in drug discovery and development. Additionally, it is employed in the preparation of sensors and catalysts due to its ability to interact with specific target molecules.
