HATU is a highly efficient peptide coupling reagent used for amide bond formation in solid-phase peptide synthesis (SPPS), solution-phase peptide synthesis, pharmaceutical research, and organic synthesis. Its full chemical name is O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate.

HATU efficiently activates carboxyl groups, enabling rapid coupling with amines to form peptide and amide bonds. It is widely preferred for challenging peptide sequences because it offers high coupling efficiency, fast reaction kinetics, and reduced racemization compared with many conventional coupling reagents.

Key Features

FeatureDetails
High Coupling EfficiencySupports rapid and high-yield amide bond formation
Low RacemizationHelps minimize epimerization during peptide coupling
SPPS CompatibleSuitable for manual and automated solid-phase peptide synthesis
Solution-Phase CompatibleCan also be used in solution-phase amide coupling reactions
Useful for Difficult SequencesSuitable for sterically hindered and complex peptide substrates
Versatile Research UseIdeal for peptide synthesis, organic synthesis, drug discovery, and bioconjugation
