Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, to construct biaryl and styryl frameworks for pharmaceuticals and functional materials. Its boronic acid group enables efficient carbon-carbon bond formation under mild conditions. Commonly applied in the development of fluorescent probes and conjugated organic compounds due to the extended π-system formed after coupling. Also utilized in medicinal chemistry for building blocks in drug discovery and in materials science for designing organic semiconductors.
