This chemical is primarily used in the field of peptide synthesis, where it serves as a protected form of L-homoserine. The fluorenylmethoxycarbonyl (Fmoc) group acts as a protecting group for the amine functionality, while the benzyl group protects the hydroxyl group. This dual protection allows for selective deprotection during the synthesis process, enabling the precise construction of complex peptides. It is particularly valuable in solid-phase peptide synthesis (SPPS), where sequential addition of amino acids is required. The compound ensures that the homoserine residue is incorporated accurately without unwanted side reactions, making it essential for producing peptides with high purity and specificity for research, pharmaceutical development, and biochemical studies.
