Used primarily as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boronate ester group facilitates efficient and selective coupling with aryl or heteroaryl halides under palladium catalysis. Commonly employed in the preparation of complex organic molecules, including active pharmaceutical ingredients (APIs), where reliable reactivity and stability are required. Also utilized in materials science for constructing conjugated systems in organic electronics.
