Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. It serves as a building block for bioactive molecules due to its ability to cross the blood-brain barrier and interact with neurological receptors. Commonly employed in the preparation of antidepressants and antipsychotics, it enables structural modification to enhance potency and selectivity. Also utilized in research settings for designing novel piperazine-based therapeutics with improved pharmacokinetic profiles.
