Used in pharmaceutical research as a key intermediate in the synthesis of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its structure supports the development of compounds targeting neurological disorders such as depression and anxiety. The phenolic and piperidine functional groups enable molecular modifications for optimizing drug potency and selectivity. Also employed in the preparation of receptor ligands for studying neurotransmitter pathways. Its hydrobromide salt form enhances stability and solubility for use in aqueous-based reactions.
