Application:

Ethyl 1-Hydroxy-1H-1,2,3-Triazole-4-Carboxylate (HOCt) (CAS: 137156-41-3) is widely used in solid phase peptide synthesis (SPPS). HOCt is a triazole-based coupling reagent used in solid-phase peptide synthesis with Fmoc-protected amino acids. HOCt requires the presence of a carbodiimide reagent such as DIC and has a high coupling efficiency with suppression of racemisation.
