Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and antimicrobial agents. Its structure allows for functionalization at key positions, making it valuable in medicinal chemistry for constructing quinoline-based bioactive molecules. It is also employed in research settings to explore new heterocyclic compounds with potential therapeutic properties. Due to the presence of electron-withdrawing groups, it serves as a useful substrate in nucleophilic aromatic substitution reactions, facilitating the introduction of various side chains in drug design.
