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 (CNS) active agents. Its cyclopropane core with fluorine substituents enhances metabolic stability and bioavailability, making it valuable in medicinal chemistry for improving drug potency and resistance to oxidative degradation. Commonly employed in structure-activity relationship (SAR) studies to optimize drug candidates targeting neurological disorders.
