Used as an intermediate in the synthesis of quinoline-based pharmaceuticals, particularly in the development of antimalarial and antibacterial agents. Its structure supports the construction of bioactive molecules due to the presence of reactive functional groups and the quinoline core, known for its pharmacological activity. Also employed in research for developing fluorescent probes and dyes, leveraging the inherent photophysical properties of the quinoline scaffold. The ester and hydroxyl groups allow for further chemical modifications, making it valuable in medicinal chemistry and materials science.
