Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. Its structure supports the creation of bioactive molecules due to the presence of both aldehyde and piperazine functionalities, enabling diverse chemical modifications. Commonly employed in the preparation of selective receptor ligands, including those targeting serotonin and dopamine receptors. Also utilized in research settings for generating novel analogs in medicinal chemistry programs aimed at treating neurological and psychiatric disorders.
