Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic compounds. Commonly employed in cross-coupling reactions, such as Suzuki and Heck reactions, to introduce pyridone scaffolds into target molecules. Also utilized in the preparation of agrochemicals and in materials science for designing nitrogen-containing organic semiconductors.
