Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders. Its structure allows for selective modification, making it valuable in medicinal chemistry for creating analogs with improved pharmacokinetic properties. Commonly employed in research settings to construct more complex piperazine-based drug candidates. Also utilized in the preparation of receptor ligands, especially in studies involving serotonin and dopamine receptors. Suitable for use in combinatorial chemistry and high-throughput screening due to its stability and reactivity profile.
