Used as an intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biaryl compounds in pharmaceutical and agrochemical research. Its boronate ester group enables efficient carbon-carbon bond formation under palladium catalysis. Commonly applied in the development of conjugated organic materials, including semiconductors and fluorescent dyes. Also utilized in medicinal chemistry for constructing complex heterocyclic systems targeting kinase inhibitors and anti-inflammatory agents.
