Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its spirocyclic structure provides rigidity and stereochemical control, making it valuable in drug design for enhancing metabolic stability and binding selectivity. Commonly employed in the development of gamma-aminobutyric acid (GABA) analogs and other neuroactive agents. Also utilized in agrochemicals for creating structurally complex molecules with improved environmental stability.
