Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. It serves as a building block for gamma-aminobutyric acid (GABA) analogs, which are important in the treatment of neurological disorders such as epilepsy, neuropathic pain, and anxiety. Its structural features allow for modification to enhance blood-brain barrier penetration and receptor specificity. Also employed in research settings for exploring new bioactive molecules and structure-activity relationships in neuropharmacology.
