This chemical is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a building block for the incorporation of N-methyl-D-serine residues into peptide chains. The Fmoc (fluorenylmethyloxycarbonyl) group acts as a protective group for the amino group, ensuring selective deprotection during synthesis. The tert-butyl (tBu) group protects the hydroxyl side chain of serine, preventing unwanted reactions. This compound is especially valuable in the synthesis of complex peptides and peptidomimetics, where precise control over stereochemistry and side-chain protection is crucial. It is commonly employed in pharmaceutical research and development for creating peptide-based drugs, as well as in biochemical studies to investigate protein structure and function.
