Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical research. Its boronate ester group facilitates carbon-carbon bond formation under mild conditions, making it valuable in the development of active pharmaceutical ingredients (APIs) and functionalized aromatic compounds. The ethyl ester moiety allows further derivatization, such as hydrolysis or amidation, adding versatility in drug discovery and materials science.
