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 (CNS) active agents. Its structure allows for the introduction of fluorinated aromatic moieties, which can enhance metabolic stability and binding affinity in drug molecules. Commonly employed in medicinal chemistry for constructing bioactive molecules targeting neurological disorders. Also utilized in the preparation of fluorinated analogs in structure-activity relationship (SAR) studies to optimize drug potency and pharmacokinetic properties.
