| Application: | • 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 |
