설명

애플리케이션

• Non-explosive replacement for HOBt and HOAt with at least comparable performance to HOAt
• Outperforms HOAt in sterically demanding peptide bond formations
• Compatible with carbodiimide-mediated; solution and solid phase peptide coupling;
• Less epimerization than HOBt in fragment condensation reactions
• K-salt especially useful in peptide coupling on mild acid-labile resins such as 2-chlorotrityl; leading to minimal to no cleavage of the peptide from the resin due to its more alkaline character
• K-salt has a higher melting point than OxymaPure
