Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key building block for constructing biaryl and heterobiaryl systems in pharmaceutical and agrochemical synthesis. Its boronate ester group enables efficient and selective carbon-carbon bond formation under mild conditions. The presence of a phenolic hydroxyl group allows for further functionalization or protection, offering versatility in multi-step organic synthesis. It is particularly valuable in the preparation of conjugated organic materials for optoelectronics and liquid crystals due to the extended aromatic framework. Its stability and reactivity profile make it suitable for use in automated synthesis and library generation in drug discovery.
