Used as a key intermediate in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of kinase inhibitors and other targeted therapies. Its structure allows for selective modification in drug design, enabling improved solubility and binding affinity. Commonly employed in the preparation of peptide mimetics and as a protecting group strategy in multi-step organic synthesis. Also utilized in the creation of functionalized polymers and surface coatings where controlled amine reactivity is required.
