Widely used in cross-coupling reactions, especially in Suzuki-Miyaura coupling, to introduce the 2-chloropyridine moiety into complex organic molecules. This compound serves as a key building block in the synthesis of pharmaceuticals, agrochemicals, and functional materials due to its reactivity with aryl and heteroaryl halides in the presence of palladium catalysts. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in medicinal chemistry for constructing biaryl systems. Commonly employed in late-stage functionalization where stability and selectivity are critical.
