Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules targeting central nervous system disorders. Its structure allows for selective modification, making it valuable in creating novel receptor agonists or antagonists. Commonly employed in medicinal chemistry for constructing piperazine-based drug candidates with improved metabolic stability and binding affinity. Also utilized in the preparation of protease inhibitors and kinase modulators due to its favorable conformational properties. Suitable for solid-phase and solution-phase peptide-like synthesis in drug discovery research.
