Used as a key intermediate in the synthesis of active pharmaceutical ingredients, particularly in the development of gamma-aminobutyric acid (GABA) analogs. Its spirocyclic structure provides conformational rigidity, enhancing binding selectivity to neurological targets. Employed in research for central nervous system agents, including anticonvulsants and neuropathic pain modulators. Also utilized in the preparation of novel heterocyclic compounds for drug discovery due to its stability and functional group compatibility.
