Ethyl (hydroxyimino)cyanoacetate potassium salt Chemical Properties,Usage,Production

Chemical Properties

Bright yellow powder

Uses

Useful in peptide coupling on mild acid-labile resins with minimal to no cleavage of the peptide from the resin due to its more alkaline character. This can be used to replace the explosive HOBt and HOAt.

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
