Hexafluorophosphate Azabenzotriazole Tetramethyl Uronium (HATU) is a reagent used in peptide coupling. You can purchase this chemical in three catalog sizes: 25g, 100g or 250g, but also good for bulk quantity. HATU is a key chemical used to form a coupling reaction, creating a formation as part of peptide synthesis.




HBTU would be the most employed aminium-based coupling reagent in peptide synthesis due to its low cost, excellent activation, racemization suppression, and good solubility and stability. HBTU normally is used in combination with a base like diisopropylethyl amine.



HCTU is an aminium coupling reagent used during the process of peptide synthesis. Peptide synthesis is important within chemistry, allowing us to create new peptides and bonds (this is the backbone of proteins). HCTU is available in three catalog sizes: 25g, 100g or 250g, but also good for bulk quantity.
