Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antimicrobial agents. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in cross-coupling reactions to introduce the naphthyridine scaffold into bioactive molecules. Also utilized in the preparation of fluorescent probes and materials for optoelectronic applications due to its electron-deficient aromatic core.
