Used primarily in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key boronic ester reagent in the synthesis of biaryl and heterobiaryl structures. Its pyrrolopyridine core makes it valuable in pharmaceutical and agrochemical research, especially in the development of kinase inhibitors and other bioactive molecules. The boronate ester group allows for efficient and selective carbon-carbon bond formation under mild conditions, making it suitable for late-stage functionalization in drug discovery. It is also employed in materials science for constructing conjugated organic frameworks used in optoelectronic devices.
