Used primarily in organic synthesis as a building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of biaryl structures in pharmaceuticals and agrochemicals. The aldehyde and boronic ester functionalities allow sequential and selective transformations, making it valuable in the preparation of complex organic molecules. Its carboxylic acid group facilitates conjugation to amines or alcohols, useful in polymer chemistry and bioconjugation. Commonly employed in materials science for designing organic semiconductors and metal-organic frameworks (MOFs) due to its rigid aromatic backbone and multiple reactive sites.
