Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antimicrobial agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for designing bioactive molecules. Commonly employed in cross-coupling reactions to introduce the naphthyridine scaffold into target compounds, enhancing binding affinity to specific enzyme active sites. Also utilized in research settings for the preparation of fluorescent probes and heterocyclic compounds with potential therapeutic applications.
