Widely used in cross-coupling reactions, especially in Suzuki-Miyaura coupling, to construct carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boronate ester group readily reacts with aryl or heteroaryl halides in the presence of palladium catalysts, enabling efficient assembly of complex pyridine-based structures. Commonly employed in the development of active pharmaceutical ingredients (APIs) where halogenated pyridine motifs are required. Also utilized in materials science for synthesizing conjugated organic molecules used in electronic devices. The presence of both bromo and chloro substituents allows for selective, stepwise functionalization, making it a valuable building block in multi-step synthetic routes.
