Used primarily in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial drugs due to its structural similarity to quinine. It serves as a key intermediate in organic synthesis, aiding in the creation of complex molecules for medicinal chemistry. Additionally, it is employed in the production of dyes and pigments, leveraging its quinoline backbone for color stability. In research, it is utilized as a building block for studying heterocyclic compounds and their biological activities. Its derivatives are also explored for potential antimicrobial and anticancer properties.
