Used as an important pharmaceutical intermediate in the synthesis of bioactive molecules, particularly in the development of central nervous system (CNS) agents. Its structure allows for selective modification, making it valuable in creating dopamine or serotonin receptor modulators. Commonly employed in medicinal chemistry for constructing complex piperazine-based drug candidates. Also utilized in the preparation of kinase inhibitors and antipsychotic drug analogs due to its favorable solubility and binding properties.
