Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and plant growth regulators. Its structure allows for selective functionalization, making it valuable in constructing nitrogen-containing heterocyclic compounds. It is also employed in the preparation of chiral ligands and catalysts used in asymmetric synthesis. Due to the aldehyde and electron-deficient pyridine ring, it readily participates in condensation and coupling reactions, enabling the formation of complex molecules in fine chemical manufacturing.
