Fmoc-Serinol(tBu) is widely used in peptide synthesis as a building block. It serves as a protected form of serinol, allowing for the controlled assembly of peptide chains. The Fmoc group provides temporary protection for the amine functionality, while the tBu group safeguards the hydroxyl group during the synthesis process. This compound is particularly valuable in solid-phase peptide synthesis (SPPS), where it helps in the stepwise construction of peptides with high precision. Its application ensures the selective deprotection and coupling of amino acids, facilitating the production of complex peptides and proteins for research, pharmaceuticals, and biotechnology.
