Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its structure supports the creation of bioactive molecules due to the presence of a piperazine ring, which is commonly found in drugs targeting neurological and psychiatric conditions. It is also employed in medicinal chemistry research for building blocks in the design of new therapeutic agents, including antipsychotics, antidepressants, and receptor modulators. Additionally, it serves as a protected form of phenylpiperazine in multi-step organic syntheses, allowing selective reactivity.
