Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor ligands and central nervous system agents. It serves as a building block in the preparation of pyridine-based compounds with potential biological activity. The chloride at position 4 and ester groups at positions 2 and 6 allow for further functionalization, providing flexibility in synthetic routes for complex molecules. Commonly employed in medicinal chemistry for constructing complex heterocyclic systems. Also utilized in research settings for the design of novel bioactive molecules and in the optimization of drug candidates targeting neurological disorders.
