Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, to construct biaryl frameworks found in pharmaceuticals and agrochemicals. The cyano group allows further functionalization, enabling the synthesis of complex molecules. Its boronic acid moiety makes it a valuable building block in medicinal chemistry for developing enzyme inhibitors and receptor ligands. Also applied in materials science for designing fluorescent probes and conjugated polymers due to its electronic properties.
