Used primarily in peptide synthesis as a protected derivative of alpha-methyl-D-tryptophan. The compound contains dual protection—Fmoc on the amine and Boc on the carboxylic acid—allowing selective deprotection and stepwise assembly of complex peptides. Its structure supports solid-phase peptide synthesis (SPPS), where the Fmoc group enables mild base cleavage while the Boc group remains stable, ensuring precise control over coupling reactions. Commonly used in the preparation of biologically active peptides and peptidomimetics, especially in pharmaceutical research and development.
