Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules targeting central nervous system disorders. Its structure allows for easy modification, making it valuable in creating analogs for drug discovery. Commonly employed in the preparation of receptor agonists and antagonists due to the presence of functional groups that enhance binding affinity. Also utilized in the synthesis of novel compounds with potential antipsychotic, antidepressant, or anxiolytic activity. Its piperazine and ester moieties contribute to improved solubility and metabolic stability in lead compounds.
