Used primarily in cross-coupling reactions, this compound serves as a key building block in the synthesis of pharmaceuticals and agrochemicals. Its boronate ester group enables efficient Suzuki-Miyaura coupling, allowing the formation of carbon-carbon bonds with aryl or heteroaryl halides under palladium catalysis. It is especially valuable in medicinal chemistry for constructing complex pyridine-based scaffolds found in bioactive molecules. The presence of chlorine atoms offers additional sites for selective functionalization, enabling further structural diversification in drug discovery and materials science.
