1-(4-Fluorophenyl)piperazine Hydrochloride丨CAS 16141-90-5

1-(4-Fluorophenyl)piperazine hydrochloride is an important chemical intermediate widely used in medicinal chemistry and pharmaceutical research. It serves as a building block for the synthesis of a variety of psychoactive compounds, including antidepressants, anxiolytics, and serotonergic agents. Its piperazine core and para-fluorophenyl substitution make it valuable for designing molecules that interact with neurotransmitter receptors, such as serotonin and dopamine receptors. The compound is also utilized in the development of experimental drugs, receptor ligands, and bioactive heterocycles. Beyond pharmaceuticals, it is applied in chemical research for creating novel nitrogen-containing heterocyclic frameworks.

The compound offers several advantages due to its well-defined piperazine scaffold and para-fluoro substitution. The fluorine atom improves metabolic stability, lipophilicity, and binding affinity of derivatives, enhancing pharmacological properties. Its hydrochloride salt form increases water solubility, facilitating handling, formulation, and purification in laboratory and industrial processes. The piperazine ring provides chemical versatility for further derivatization, such as N-substitution, acylation, or alkylation, enabling the synthesis of a wide range of bioactive compounds. Additionally, its stable and reproducible structure supports reliable multi-step synthesis in drug discovery and chemical research.
