As part of the peptide chain construction in Semaglutide synthesis, Ste-γ-Glu-AEEA-AEEA-OSU (CAS No. 1169630-40-3, C₃₉H₆₆N₄O₁₅) acts as an activated intermediate designed for efficient coupling. It combines a stearoylated γ-glutamic acid backbone with two AEEA spacers and an N-hydroxysuccinimide (OSu) ester, making it well-suited for integration into long-chain peptides. This off-white powder offers a purity of ≥98% and a molecular weight of 831.0 g/mol. It’s supplied in 25 kg fiber drums and should be kept sealed at –20 °C ±5 °C to preserve its reactivity and overall stability.
