Used in the synthesis of pharmaceutical intermediates, particularly in the development of nicotinic receptor ligands for neurological research. Serves as a building block in medicinal chemistry for creating compounds with potential cognitive-enhancing or neuroprotective effects. Also applied in the preparation of metal-organic frameworks (MOFs) due to its ability to coordinate with metal ions through both carboxylic acid and pyridine functionalities. Its structural features make it useful in designing sensors and functional materials.
