Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biologically active compounds, particularly in pharmaceutical research. Its boronate ester group enables efficient carbon-carbon bond formation, making it valuable in constructing complex heterocyclic systems found in drug candidates. Commonly applied in the development of kinase inhibitors and other targeted therapies due to the pyrrolopyridine core’s strong binding properties with biological targets. Also utilized in materials science for creating organic electronic compounds where nitrogen-rich heterocycles enhance electron transport features.
