Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor ligands and other bioactive molecules targeting neurological disorders. Commonly employed in medicinal chemistry for constructing pyridine-containing analogs due to its reactive ester group and aromatic core. Also utilized in agrochemical research for designing novel pesticides with improved selectivity. Its structural features make it valuable in fragment-based drug discovery and library synthesis for high-throughput screening.
