This compound is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. It serves as a protected form of homoserine, where the FMOC (fluorenylmethyloxycarbonyl) group protects the amino group, and the TRT (trityl) group protects the hydroxyl group. This protection is crucial to prevent unwanted side reactions during the peptide chain assembly process. It is especially valuable in synthesizing peptides that require homoserine residues, enabling precise control over the sequence and structure of the final peptide product. Its application is common in pharmaceutical research, biotechnology, and the development of therapeutic peptides, where high purity and specificity are essential.
