Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) involving substituted anilines and piperazine derivatives. Its structure supports the formation of biologically active molecules, making it valuable in medicinal chemistry for drug discovery. Commonly employed in the production of psychotropic and neurologically targeted drugs due to the piperazine and aniline moieties, which are known for their receptor-binding properties. Also utilized in research settings for creating novel compounds with potential antipsychotic, antidepressant, or antihistaminic activity. The dihydrochloride form enhances solubility and stability, facilitating its use in aqueous reaction conditions and purification processes.
