Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its boronic acid group enables Suzuki-Miyaura cross-coupling reactions, making it valuable in constructing biaryl structures found in bioactive molecules. Also employed in the preparation of protease inhibitors and other therapeutic agents targeting inflammatory and metabolic diseases. Its pyridine backbone enhances binding affinity to biological targets, improving drug efficacy. Additionally, it serves in chemical biology for labeling and sensing applications due to its selective reactivity.
