Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with central nervous system activity. Its structure supports the creation of compounds with potential antipsychotic, antidepressant, or anxiolytic effects. The difluoroethyl group enhances metabolic stability and bioavailability, making it valuable in medicinal chemistry for optimizing drug candidates. It is also employed in research settings to explore new bioactive molecules and structure-activity relationships in piperazine-based derivatives.
