Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing nitrogen-containing heterocycles. Commonly employed in cross-coupling reactions to introduce the pyridone scaffold into larger molecules, enhancing binding affinity and metabolic stability in drug candidates. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its reactivity and structural properties.
