Fmoc-L-Ser(tBu)-OH (CAS No. 71989-33-8) is a side-chain protected serine derivative frequently used in solid-phase peptide synthesis. The Fmoc group protects the amino functionality, while the tert-butyl group ensures stability of the hydroxyl side chain during elongation. Thanks to its compatibility with standard synthesis protocols, it's particularly suitable for assembling GLP-1 analogues such as Semaglutide and Tirzepatide. This compound is available as a white crystalline powder, with 99% min purity, molecular formula C₂₂H₂₅NO₅, and molecular weight of 383.4 g/mol.
