1-Hydroxybenzotriazole hydrate Usage And Synthesis
Chemical PropertiesWhite to off-white powder
Usesadditive for oligonucleotide couplings and in racemization-free peptide couplings
Uses1-Hydroxybenzotriazole hydrate can be used as a condensation reagent to prepare:
  • Poly-γ-glutamic acid methyl ester from a dimer of γ-glutamic acid.

  • Oxadiazoles via cyclo condensation of amidoximes with trifluoroacetic anhydride or benzoic acid derivatives.


UsesA common additive for peptide coupling.
General Description1-Hydroxybenzotriazole is a coupling reagent used to synthesize amides by the condensation reaction between the activated ester/acid and the amino group of protected amino acids. It is also used as a racemization suppressor during peptide synthesis.
