This compound is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a building block for introducing D-serine with a benzyl-protected side chain into peptide chains. The FMOC group provides temporary protection for the amino group during synthesis, which can be selectively removed under mild basic conditions. Its application is crucial in the production of custom peptides for research in biochemistry, pharmaceuticals, and biotechnology. It is also utilized in the development of peptide-based drugs and bioactive molecules, where the specific stereochemistry and protection of functional groups are essential.
