Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its spirocyclic structure and protected amine functionality make it valuable in medicinal chemistry for constructing complex amines and heterocycles. Commonly employed in the preparation of kinase inhibitors and receptor modulators due to its favorable steric and electronic properties. Also utilized in the synthesis of agrochemicals and functional materials where a rigid, sterically hindered diamine scaffold is required.
