Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) active compounds. Its rigid cyclopropyl structure with defined stereochemistry makes it valuable for designing inhibitors and modulators of neurotransmitter activity. Commonly employed in the preparation of monoamine oxidase inhibitors (MAOIs), where the (1S,2R) configuration contributes to selective binding and enhanced metabolic stability. Also utilized in research settings for probing enzyme mechanisms and developing novel antidepressants or neuroprotective agents.
