Used in the synthesis of pharmaceutical intermediates, particularly in the development of nitrogen-containing heterocyclic compounds with potential biological activity. Its structure serves as a building block in medicinal chemistry for designing compounds that may exhibit antimicrobial, anti-inflammatory, or anticancer properties. Commonly employed in research settings for constructing more complex molecules through functional group transformations or coupling reactions. Also utilized in the preparation of fluorescent dyes and optoelectronic materials due to the extended π-conjugation of the naphthyridine core.
