Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective binding and modification in drug design, enhancing potency and specificity. Commonly employed in research settings for constructing complex heterocyclic systems in medicinal chemistry. Also utilized in the preparation of analogs for structure-activity relationship (SAR) studies due to its rigid framework and reactive ethynyl group, which supports coupling reactions like Sonogashira. Shows utility in creating novel pyridine-based bioactive molecules with potential neurological and antiviral applications.
