Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its structure supports the creation of bioactive molecules with improved metabolic stability and receptor binding affinity. Commonly employed in medicinal chemistry for constructing fluorinated analogs to enhance drug potency and pharmacokinetic properties. Also utilized in the preparation of agrochemicals and functional materials where aromatic amine and fluorine moieties contribute to desired biological or physical activity.
