1-Benzylpiperazine dihydrochloride is primarily used in research settings as a reference compound in the study of psychoactive substances. It has been investigated for its effects on the central nervous system, particularly in relation to serotonin and dopamine receptors. Researchers utilize it to understand the pharmacological properties and potential risks associated with piperazine derivatives. Additionally, it serves as a precursor or intermediate in the synthesis of other chemical compounds, aiding in the development of new pharmaceuticals or experimental drugs. Its application is strictly limited to controlled laboratory environments due to its psychoactive nature and potential for misuse.
