Used as an intermediate in the synthesis of quinolone-based pharmaceuticals, particularly in the development of antimalarial and antibacterial agents. Its structure supports the construction of complex heterocyclic systems important in medicinal chemistry. Commonly employed in research settings to prepare bioactive molecules through functional group transformations at the ester and aromatic positions. Also utilized in the optimization of drug candidates due to its favorable reactivity and ability to enhance pharmacokinetic properties in final compounds.
