Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents and receptor antagonists. Its structure supports the construction of bioactive molecules due to the presence of a piperazine ring and a chlorophenoxy moiety, which are common in drugs targeting neurological and cardiovascular conditions. Commonly employed in medicinal chemistry for modifying pharmacokinetic properties such as solubility and metabolic stability. Also utilized in research settings to develop novel analogs for structure-activity relationship studies.
