Used primarily as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of selective receptor modulators targeting serotonin and norepinephrine receptors. Its structural features, including phenoxy and piperazine groups, enable interaction with central nervous system targets and facilitate crossing the blood-brain barrier, making it valuable in the research of neuroactive compounds.

Commonly employed in the preparation of experimental drugs aimed at treating neurological and psychiatric disorders, including anxiety, depression, cognitive dysfunction, chronic psychiatric conditions, Parkinson's disease, and neurodegenerative impairments.

Also utilized in structure-activity relationship (SAR) studies to optimize pharmacokinetic properties such as metabolic stability and receptor binding affinity. However, it remains in the research and development stage, with limited clinical use, and further studies on safety, toxicity, and absorption are required.
