Used primarily as a chiral building block in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) active compounds. Its structural motif is valuable in creating selective ligands for neurotransmitter receptors, including dopamine and serotonin receptors. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the bromine substituent allowing further functionalization via cross-coupling reactions. Also utilized in asymmetric synthesis to introduce stereochemical control in complex molecule construction.
