Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic receptor ligands and drugs targeting neurological disorders. It serves as a building block in medicinal chemistry for developing compounds with potential cognitive-enhancing or neuroprotective effects. Also employed in the preparation of pyridine-based agrochemicals and specialty polymers due to its ability to form stable coordination complexes and participate in coupling reactions. Its carboxylic acid group allows easy derivatization into esters, amides, and other functional groups for tailored applications in research and development.
