1. additive for oligonucleotide couplings and in racemization-free peptide couplings
2. 1-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.
3. A common additive for peptide coupling.
General Description
1-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.
Check Digit Verification of cas no
The CAS Registry Mumber 123333-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,3 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 123333-53:
(8*1)+(7*2)+(6*3)+(5*3)+(4*3)+(3*3)+(2*5)+(1*3)=89
89 % 10 = 9
So 123333-53-9 is a valid CAS Registry Number.
