20-(tert-Butoxy)-20-oxoicosanoic acid (CAS No. 683239-16-9, molecular formula C₂₄H₄₆O₄) is a white to beige solid used as a lipid-like side chain intermediate in peptide synthesis. Its tert-butyl ester structure offers enhanced hydrophobicity, which can contribute to improved peptide stability and pharmacokinetics. This compound is commonly involved in the synthesis of GLP-1 receptor agonists such as Semaglutide and Tirzepatide. It is supplied in 25 kg fibre drums and should be stored at room temperature in a dry, well-sealed container.
