Fmoc-L-Asn(Trt)-OH (CAS No. 132388-59-1) is a protected L-asparagine derivative used in Fmoc-based solid-phase peptide synthesis. The Fmoc group protects the α-amino group, while the Trt group stabilizes the amide side chain, preventing cyclization or side reactions. This dual protection is especially useful in the synthesis of GLP-1 analogs like Semaglutide and Tirzepatide.
