Used in organic synthesis as a chiral building block for pharmaceuticals, particularly in the development of central nervous system agents. Its rigid cyclopropane structure and functional groups make it valuable for designing bioactive molecules with specific stereochemistry. Commonly employed in the preparation of dopamine and serotonin receptor ligands due to the structural similarity with biologically active phenylalkylamines. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies, helping optimize potency and selectivity of drug candidates.
