Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, to construct biaryl compounds for pharmaceutical and agrochemical development. The carboxylic acid group allows for further functionalization or conjugation, while the ethoxy group enhances water solubility and compatibility with various solvents, facilitating reaction control. This combination makes it valuable in the design of active pharmaceutical ingredients (APIs), molecular probes, and special materials such as luminescent or conductive compounds. Its boronic acid moiety enables selective binding to diols, useful in sensor technologies and targeted drug delivery systems. Commonly employed in the preparation of complex intermediates where both coupling and derivatization are required.
