Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. It serves as a chiral building block for gamma-aminobutyric acid (GABA) analogs, which are explored for their anticonvulsant, analgesic, and neuroprotective properties. Its structural features allow for modification to enhance blood-brain barrier penetration and receptor selectivity. Also employed in research for designing novel bioactive molecules and enzyme inhibitors.
