Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antimicrobial agents. Its structure supports the formation of bioactive molecules with potential activity against certain cancers and infectious diseases. Commonly employed in medicinal chemistry research for constructing naphthyridine-based scaffolds that enhance binding affinity to target enzymes. Also utilized in the preparation of fluorescent probes due to its favorable photophysical properties, useful in biochemical imaging and assay development.
