Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of complex pyrimidine derivatives in pharmaceutical and agrochemical research. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in the development of active pharmaceutical ingredients (APIs) and functional materials. Commonly employed in medicinal chemistry for building blocks in drug discovery, especially in kinase inhibitors and other bioactive molecules. Stable and compatible with a wide range of functional groups, allowing for high selectivity and yield in coupling reactions.
