Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of pyridine-containing compounds with biological activity. It serves as a building block in the preparation of agrochemicals and functionalized heterocycles. Its keto ester functionality allows for versatile chemical transformations, including condensation, reduction, and cyclization reactions, making it valuable in medicinal chemistry and organic synthesis. Commonly employed in the production of nicotinic receptor ligands and other bioactive molecules.
