Other Notes
Recent studies show that crystal and solution structure of this coupling agent is a guanidinium N-oxide and not an uronium compound3; Non-hygroscopic, extremely reactive reagent for peptide coupling. It is an analogue of the bis(tetramethylene) derivative described recently4
Packaging
5 g in glass bottle
Application
Reactant used for: comparison of racemization during peptide coupling1 esterification of nucleosides to solid phase supports for oligonucleotide synthesis2
