Used as an intermediate in organic synthesis, particularly in the preparation of gamma-aminobutyric acid (GABA) analogs and pharmaceutical compounds. It serves as a building block for nitrogen-containing heterocycles and is employed in the synthesis of bioactive molecules, including central nervous system agents. The nitro group allows for further functionalization through reduction to an amine, enabling peptide-like chain extensions. Commonly applied in medicinal chemistry research for developing potential neuroactive drugs.
