Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It serves as a building block for developing drug candidates targeting central nervous system disorders and inflammatory conditions. The presence of the nitro and trifluoromethyl groups enhances its utility in structure-activity relationship studies, enabling modifications to improve potency and metabolic stability. Commonly employed in medicinal chemistry for constructing piperazine-based derivatives with potential antipsychotic, antidepressant, or anticonvulsant activity.
