Oxyma Pure used with DIC produces peptides with increased yield and decreased epimerization when used as an alternative to HOBt1 . This safe, non-explosive auxiliary nucleophile works with carbodiimide coupling strategies to provide the best results for a peptide synthesis. Additionally, the use of DIC/Oxyma avoids side reactions associated with high levels of base (≥ 1 equiv. DIEA) using onium salt methods such as HBTU/DIEA.
