Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its aldehyde functionality allows for easy derivatization, making it valuable in building complex heterocyclic structures. Commonly employed in medicinal chemistry for constructing pyridine-based scaffolds, which are prevalent in drug discovery programs targeting cancer, inflammation, and central nervous system disorders. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its structural compatibility with bioactive molecules.
