Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules targeting central nervous system disorders. Its rigid cyclobutane scaffold with a cis-fluorine substituent enhances metabolic stability and influences binding selectivity in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing potency and pharmacokinetic properties of novel therapeutics. Also utilized in the preparation of fluorinated analogs to improve membrane permeability and bioavailability.
