Used primarily in organic synthesis as a building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceuticals and agrochemicals. Its aldehyde and boronate functional groups allow sequential transformations, making it valuable in the preparation of complex aromatic and heteroaromatic systems. Commonly employed in the development of luminescent materials, sensors, and conjugated polymers for optoelectronic devices. Also utilized in medicinal chemistry for constructing biaryl aldehyde intermediates in drug discovery.
