The perfect activator for peptide synthesis at elevated temperature.



OxymaPure® 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.

  • Extremely fast acylation rates
  • Non-explosive (compared to HOBt)
  • Low cost
  • Highly soluble in peptide synthesis solvents
