Used as a key building block in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical research. Its boronate ester group facilitates efficient carbon-carbon bond formation with aryl or vinyl halides under mild conditions. The carboxylic acid functionality allows for further derivatization or attachment to solid supports, making it valuable in drug discovery and materials science. Commonly employed in the preparation of naphthalene-based conjugated systems for optoelectronic applications and bioactive compound synthesis.
