Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinamide-based drugs and kinase inhibitors. It serves as a building block in medicinal chemistry for constructing pyridone rings, which are common structural motifs in bioactive molecules. Its aldehyde functionality allows for easy derivatization, enabling the formation of imines, oximes, or other functional groups important in drug design. Also employed in the preparation of nootropic agents and compounds targeting neurological disorders. Additionally, it finds use in agrochemical research for developing novel pesticides and herbicides due to its reactive scaffold.
