O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate

Description:

O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate, commonly referred to as HATU, is a coupling reagent widely used in peptide synthesis. This compound facilitates the formation of amide bonds between amino acids by activating carboxylic acids, making them more reactive towards nucleophilic attack by amines. HATU is characterized by its high efficiency and mild reaction conditions, which help preserve sensitive functional groups during synthesis. It is typically used in conjunction with a base, such as N,N-diisopropylethylamine (DIPEA), to promote the coupling reaction. The hexafluorophosphate counterion contributes to the solubility of HATU in organic solvents, enhancing its utility in various organic synthesis applications. Additionally, HATU is known for its stability and ease of handling, although it should be stored under dry conditions to prevent hydrolysis. Safety precautions are necessary when handling HATU, as it can be irritating to the skin and eyes. Overall, HATU is a valuable reagent in the field of organic and medicinal chemistry for the efficient synthesis of peptides and other amide-containing compounds.

HATU

CAS: 148893-10-1

HATU is the gold standard reagent for amide formation and peptide synthesis, both in solid and solution phase. HATU is stable, allows to achieve high yields with fast reaction rates, is extremely efficient with sterically hindered substrates and suppresses racemisation. HATU generates HOAt in situ, which forms an activated ester with a high reactivity towards amines. A side-reaction to form a guanidinium by-product may take place, and this can be suppressed by the addition of HOBt. Although HATU was originally thought to exist as an uronium salt, the X-ray structure demonstrated that it is a guanidinium N-oxide instead.
