Used in organic synthesis as an intermediate for pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its alkyne functionality allows for use in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling efficient conjugation in drug discovery and bioconjugation applications. The pyridine ring provides a structural motif common in medicinal chemistry, enhancing binding affinity to biological targets. Often employed in the synthesis of potential anticancer and anti-inflammatory agents due to its ability to modulate enzyme activity.
