Used in organic synthesis as a key intermediate in Suzuki-Miyaura cross-coupling reactions to construct biaryl or heteroaryl frameworks. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in pharmaceutical and agrochemical research for developing nitrogen-containing heterocyclic compounds. Commonly employed in the synthesis of kinase inhibitors and other bioactive molecules due to the pyrazolopyrimidine core’s biological relevance. Suitable for solid-phase and solution-phase combinatorial chemistry, supporting rapid library generation in drug discovery.
