Used in pharmaceutical research as a chiral building block for synthesizing biologically active compounds. Its structure supports the development of neuroactive agents due to the presence of a pyrrolidine ring linked to an aromatic system, which is common in central nervous system-targeting drugs. Frequently employed in the preparation of serotonin and dopamine receptor ligands. Also utilized in asymmetric synthesis where stereochemistry plays a critical role in drug efficacy. Its hydrochloride salt form improves solubility and stability, making it suitable for solution-phase reactions in medicinal chemistry.
