Used primarily in organic synthesis, especially in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key building block for constructing biaryl structures. Its boronic ester functionality allows it to react with aryl halides under palladium catalysis, enabling the formation of extended aromatic systems. This is particularly valuable in the development of pharmaceuticals, agrochemicals, and advanced materials where naphthalene-based frameworks are required. The carboxylic acid group also provides a convenient handle for further derivatization, such as amide formation or esterification, making it useful in multi-step synthesis and the preparation of functionalized organic molecules.
