Used in pharmaceutical research as a key intermediate in the synthesis of various biologically active compounds, particularly in the development of antimalarial and anticancer agents. It serves as a building block for creating complex molecules due to its quinoline structure, which is known for its medicinal properties. Additionally, it is employed in organic synthesis for the preparation of heterocyclic compounds, which are useful in drug discovery and material science. Its halogenated structure allows for further functionalization, making it versatile in chemical reactions.
