As a core intermediate in Tirzepatide synthesis, Fmoc-L-Lys[C₂₀-OtBu-γ-Glu(OtBu)-AEEA-AEEA]-OH supports the assembly of peptide chains with precise protection patterns. The presence of long-chain lipid moieties like C₂₀-OtBu and γ-Glu(OtBu) improves the physicochemical profile needed for GLP-1/GIP dual receptor targeting. Supplied as a white solid with 99% min purity, it is typically packaged in 25 kg fibre drums for efficient batch production.
