Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic acid derivatives and vitamin B3 (niacin) analogs. It serves as a building block in agrochemicals for developing herbicides and plant growth regulators. Also employed in the preparation of ligands for catalytic metal complexes in industrial processes. Its aldehyde functionality allows for easy modification in organic synthesis, making it valuable in research laboratories for creating nitrogen-containing heterocyclic compounds.
