Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs. It serves as a building block in organic reactions where its carboxylic acid group allows for easy derivatization into amides, esters, or other functional groups. Also employed in the development of agrochemicals and specialty heterocyclic compounds due to its stable pyridine ring and favorable reactivity profile. Its structure supports metal coordination, making it useful in catalysis research and ligand design.
