Used primarily as a key building block in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. Its vinylboronate ester group reacts efficiently with aryl or vinyl halides under palladium catalysis, making it valuable for constructing conjugated systems found in pharmaceuticals, agrochemicals, and advanced materials. The presence of a hydroxyl group allows for further functionalization or anchoring to polymers and surfaces, expanding its utility in medicinal chemistry and material science. Stable and easy to handle, it is preferred in multi-step syntheses requiring selective reactivity.
