Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its boronic acid functional group enables Suzuki-Miyaura cross-coupling reactions, allowing efficient construction of biaryl structures in drug molecules. It is also employed in the preparation of protease inhibitors and other bioactive agents where pyridine-based scaffolds enhance target selectivity and metabolic stability. Its compatibility with various reaction conditions makes it valuable in medicinal chemistry and combinatorial library synthesis.
