- IUPAC
- 2-Cyano-2-(hydroxyimino)acetic acid ethyl ester, potassium salt,Ethyl (hydroxyimino)cyanoacetate potassium salt
| Molecular weight | 180.20 |
|---|---|
| Empirical formula | C5H5KN2O3 |
| Assay | 97% |
| Storage temperature | 2-8°C |
| 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 |
| Melting point | 141-147 |
