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 carbon-carbon bond formation under mild conditions, making it valuable in drug discovery for building biaryl or heteroaryl scaffolds. Commonly employed in the development of kinase inhibitors and other bioactive molecules due to the stability and reactivity of the pyrimidine core. Also utilized in materials science for constructing conjugated systems in organic electronics.
