Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of biaryl compounds and heterocyclic systems prevalent in pharmaceuticals and agrochemicals. Its boronic ester group facilitates efficient and selective bond formation under mild conditions, making it valuable in drug discovery and development of functional materials. Commonly employed in the preparation of kinase inhibitors and other bioactive molecules due to the pyrimidine scaffold’s affinity for biological targets.
