Used primarily as a pharmaceutical intermediate in the synthesis of active drug substances, particularly in the development of central nervous system agents. Its structure supports the creation of compounds with neuroactive properties, making it valuable in research related to psychiatric and neurological disorders. It is also employed in the preparation of novel piperazine derivatives for structure-activity relationship (SAR) studies in medicinal chemistry. Due to its functional groups, it serves as a building block in coupling reactions and heterocyclic synthesis during drug discovery.
