Used as a key chiral building block in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) active compounds. Its rigid cyclopropane scaffold and defined stereochemistry make it valuable for constructing stereoselective drug candidates. Commonly employed in the preparation of analogs for serotonin and dopamine receptor modulators. Also utilized in asymmetric synthesis routes where the bromoaryl group allows further functionalization via cross-coupling reactions such as Suzuki or Heck reactions. Its carboxylic acid functionality enables easy derivatization into amides, esters, or other functional groups for structure-activity relationship (SAR) studies.
