Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of antibacterial and antiviral drugs. Its naphthyridine core structure contributes to binding with enzymes involved in nucleic acid synthesis, making it valuable in medicinal chemistry. Also employed in research for designing fluorescent probes due to its ability to exhibit photoluminescent properties under certain conditions. Commonly utilized in organic synthesis to build more complex heterocyclic systems for drug discovery and material science applications.
