Used primarily as a key intermediate in organic synthesis, especially in the preparation of pharmaceuticals and functional materials. Its structure allows for easy attachment to other molecules, making it valuable in solid-phase peptide synthesis and the development of protected amine derivatives. Commonly employed in the formation of Fmoc-protected amines, it helps regulate reactivity in multi-step reactions. Also utilized in the synthesis of specialty polymers and ligands for catalysis due to its stability and selective deprotection characteristics.
