Bright yellow powder | [Uses]
- 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
