Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) that require stereochemical precision. Its structure supports the development of biologically active molecules, especially in central nervous system (CNS) agents and antipsychotic drugs. The presence of both nitrile and piperazine functional groups allows for versatile chemical transformations, enabling efficient coupling reactions and ring formations in drug design. Commonly employed in medicinal chemistry for lead optimization due to its favorable solubility and stability when handled as the dihydrochloride salt.
