Used as an intermediate in the synthesis of pharmaceuticals, 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. It is also employed in the preparation of agrochemicals and organic materials where naphthyridine frameworks enhance electronic properties. Commonly utilized in research settings for building complex molecules through cross-coupling and nucleophilic substitution reactions.
