Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the development of quinolone-class antibiotics. Its structure allows for further functionalization, enabling the introduction of fluorine atoms into bioactive molecules, which can enhance metabolic stability and binding affinity. Also employed in agrochemical research for designing herbicides and fungicides due to the electron-withdrawing properties of the halogen substituents. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving aromatic ester derivatives.
