Used primarily in cross-coupling reactions, especially in Suzuki-Miyaura coupling, to construct biaryl and aryl-aryl systems in pharmaceutical and agrochemical synthesis. The boronate ester group acts as a key reactive handle, enabling efficient carbon-carbon bond formation under mild conditions. It is particularly valuable in late-stage functionalization of aromatic compounds due to its stability and selectivity. Commonly employed in the development of active pharmaceutical ingredients (APIs) and organic electronic materials where precise molecular architecture is required. Its methyl ester functionality allows for further derivatization, such as hydrolysis or reduction, expanding its utility in multi-step synthetic routes.
