Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in research settings to prepare analogs for structure-activity relationship (SAR) studies. Also utilized in the preparation of fluorescent probes and enzyme inhibitors due to its ability to mimic pyridine-based natural substrates.
