Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. It serves as a building block for hydrazone and heterocyclic ring formation, enabling the construction of bioactive molecules. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of fluorine and methoxy groups, which influence metabolic stability and binding affinity. Also utilized in the preparation of dyes and functional materials where aromatic hydrazines act as coupling agents.
