Applications

  • Recent studies show that crystal as well as solution structure of this coupling agent is a guanidinium N-oxide and not an uronium compound.
  • HBTU is attributed to various advantages, such as -very low racemization, simple reaction conditions, very short reaction time, and high yields.
