Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and bioactive molecules. Its phenolic hydroxyl and protected amine groups allow for selective functionalization, making it valuable in multi-step synthesis. Commonly employed in the construction of complex amines, peptidomimetics, and drug candidates where orthogonal protection strategies are required. The Cbz group facilitates easy deprotection under mild conditions, enabling further amine derivatization in peptide coupling or heterocycle formation.
