Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for functionalization in cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in research settings to introduce pyridine-based scaffolds into drug candidates. Also utilized in the preparation of agrochemicals and functional materials due to its reactive ethynyl and ester groups.
