Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key building block for constructing biaryl and heteroaryl frameworks in pharmaceutical and agrochemical synthesis. Its boronate ester group enables efficient and selective carbon-carbon bond formation under mild conditions. Commonly employed in late-stage functionalization of complex molecules, it allows introduction of a pyridine-carboxylate motif, which is valuable in drug discovery for modulating solubility, binding affinity, and metabolic stability. It is also used in materials science for synthesizing conjugated organic systems, such as those found in OLEDs and organic semiconductors.
