Used as a key chiral intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its cyclopropane scaffold with defined stereochemistry enhances binding selectivity in drug candidates. Commonly employed in the development of serotonin or dopamine receptor modulators due to the structural rigidity and metabolic stability provided by the fluorinated aryl-cyclopropane motif. Also utilized in asymmetric synthesis routes where stereocontrol is critical for efficacy and safety of the final active ingredient.
