Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biologically active compounds, particularly 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 complex heterocyclic systems. Commonly employed in the preparation of kinase inhibitors and other drug candidates due to the structural similarity of its pyrrolopyridine core to naturally occurring alkaloids and pharmacophores. Also utilized in materials science for constructing conjugated organic frameworks in optoelectronic devices.
