Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules targeting central nervous system disorders. Its spirocyclic structure and protected amine functionality make it valuable in medicinal chemistry for constructing complex heterocycles. Commonly employed in the preparation of kinase inhibitors and receptor modulators due to its conformational rigidity and ability to enhance metabolic stability in drug candidates. Also utilized in agrochemical research for designing novel active ingredients with improved selectivity.
