Used as a key intermediate in the synthesis of peptides, particularly in the production of peptide-based pharmaceuticals. It plays a crucial role in solid-phase peptide synthesis (SPPS) by protecting the tryptophan side chain during the assembly of peptide chains. This compound is essential in creating peptides with specific biological activities, such as hormone analogs or enzyme inhibitors. Its application extends to research in biochemistry and medicinal chemistry, where it aids in studying peptide structure and function. Additionally, it is utilized in the development of therapeutic peptides for treating various diseases, including cancer and metabolic disorders.
