Used primarily in pharmaceutical research as an intermediate in the synthesis of bioactive molecules, particularly in the development of kinase inhibitors and antipsychotic agents. Its structure supports binding to central nervous system targets, making it valuable in early-stage drug discovery for neurological disorders. Also employed in the preparation of fluorescent probes due to its ability to enhance solubility and cellular permeability in imaging agents. Commonly found in medicinal chemistry workflows for structure-activity relationship (SAR) studies involving piperazine-based derivatives.
