Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Its structure supports the development of nitrogen-containing heterocycles, which are common in medicinal chemistry. Commonly employed in the preparation of potential central nervous system agents due to the presence of the rigid polycyclic framework. Also utilized in research settings for the design of novel quinoline-based derivatives with possible antitumor, antimicrobial, or antiviral activity. The ester and carbonyl groups allow further functionalization, making it valuable in building complex molecules for drug discovery.
