Used as a key 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 corresponding alcohols or amines. Commonly employed in medicinal chemistry for building heterocyclic compounds due to its pyridine core with electron-donating methoxy group, which enhances reactivity and selectivity in coupling reactions. Also utilized in agrochemical research for designing novel pesticides and herbicides. Its structural features support improved solubility and binding affinity in final active compounds.
