Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its aldehyde functionality allows for easy derivatization, making it valuable in forming imines, oximes, or undergoing reduction to produce alcohol derivatives. Commonly employed in medicinal chemistry for constructing heterocyclic compounds with potential anti-inflammatory, antiviral, or anticancer activity. Also utilized in agrochemical research for designing novel active ingredients due to its pyridine backbone, which often contributes to enhanced metabolic stability and target selectivity.
