Used primarily in research settings as a selective norepinephrine reuptake inhibitor, this compound serves as a valuable tool for studying neurotransmitter systems in the brain. It is commonly employed in neuroscience to investigate the role of norepinephrine in mood regulation, attention, and cognitive function. Due to its high selectivity, it helps differentiate norepinephrine-related effects from those involving serotonin or dopamine pathways. It has also been used in radiolabeled form to map norepinephrine transporters in brain tissue, aiding in the development of psychiatric medications. Not intended for clinical use, it remains an important reference compound in pharmacological studies.
