Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its structure allows for efficient introduction of fluorine and nitro functional groups into complex molecules, enhancing metabolic stability and binding affinity. Commonly employed in research settings for constructing bioactive heterocycles and in the preparation of fluorescent probes due to its electron-withdrawing characteristics and ring reactivity.
