General description

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

Application

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

Uronium and Guanidinium Salts

The special need of SPPS for rapid and highly efficient coupling reagents led to the development of several new reagents starting from BOP (Benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate).

COMU-Safer and More Efficient Peptide Coupling Reagent

COMU is a non-explosive coupling agent suitable for solution phase & solid phase peptide synthesis. Its activity meets or exceeds that of HATU and its water-soluble by-product are easily removed.
