Used as a key intermediate in the synthesis of pharmaceuticals and functional materials, particularly in the development of nitrogen-containing heterocyclic compounds. Its aldehyde group enables condensation reactions to form Schiff bases, which are valuable in coordination chemistry for creating metal-organic frameworks (MOFs) and catalysts. Also employed in the preparation of pyridine-based ligands and optoelectronic materials due to its aromatic and nitrogen-donor properties. Shows potential in medicinal chemistry for designing bioactive molecules targeting various diseases.
