Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex pyrimidine derivatives in pharmaceutical and agrochemical research. Its boronate ester group facilitates efficient carbon-carbon bond formation under mild conditions, making it valuable in drug discovery for building bioactive molecules. Commonly employed in the development of kinase inhibitors and other therapeutic agents where precise molecular architecture is critical. Also utilized in materials science for constructing conjugated systems in organic electronics.
