Used as a key intermediate in the synthesis of pharmaceuticals and bioactive molecules, particularly in the development of protected amino alcohol derivatives. Its phenolic hydroxyl and Boc-protected amine groups allow for selective functionalization, making it valuable in medicinal chemistry for building complex structures. Commonly employed in the preparation of ligands, catalysts, and enzyme inhibitors where controlled reactivity and stability are required. Also utilized in solid-phase synthesis and combinatorial chemistry due to its orthogonal protecting group strategy.
