Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block for heterocyclic compounds due to the reactivity of the ester groups and the pyridine ring. Commonly employed in the synthesis of metal-organic frameworks (MOFs) and coordination polymers, where it acts as a ligand for metal ions. Also utilized in the development of fluorescent materials and sensors owing to its ability to chelate metals and participate in electron transfer processes. Its derivatives show potential in medicinal chemistry, especially in compounds targeting central nervous system disorders and inflammation.
