(3-Bromo-4-chlorophenyl)boronic acid is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is essential for forming carbon-carbon bonds, enabling the construction of complex organic molecules, including pharmaceuticals, agrochemicals, and advanced materials. Its boronic acid group acts as a key intermediate, facilitating the coupling with aryl or vinyl halides in the presence of a palladium catalyst. Additionally, it is employed in the development of bioactive compounds and as a building block in medicinal chemistry for drug discovery. Its unique structure, with bromo and chloro substituents, also makes it useful in designing molecules with specific electronic and steric properties.
