Used primarily as a reagent in organic synthesis, especially in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds. Its boronic ester functionality provides enhanced stability and handling compared to the corresponding boronic acid. The 4-bromo substituent allows for further functionalization or coupling, making it a valuable building block in the synthesis of complex organic molecules, including pharmaceuticals and agrochemicals. Commonly employed in the development of conjugated systems such as biaryls and extended π-frameworks found in materials science and medicinal chemistry.
