Description

General description

HBTU is a peptide coupling agent used in Fmoc-based solid-phase peptide synthesis.

Application

HBTU is a peptide coupling agent for peptide synthesis. It has also been used in standard Fmoc-based solid-phase peptide synthesis (SPPS) protocol.

Recent studies show that crystal as well as solution structure of this coupling agent is a guanidinium N-oxide and not an uronium compound; Coupling reagent for peptide synthesis; advantages are: very low racemization, simple reaction conditions, very short reaction time, and high yields.
