Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and chiral drugs. Its structure supports the construction of complex piperazine-based frameworks common in central nervous system agents, enzyme inhibitors, and receptor antagonists. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of functional handles for further derivatization. Also utilized in asymmetric synthesis where the chiral center aids in stereoselective transformations.
