Description

O-(3,4-Dihydro-4-oxo-1,2,3-benzotriazin-3-yl)-N,N,N?,N?-tetramethyluronium tetrafluoroborate (2-(3,4-dihydro-4-oxo-1,2,3-benzotriazin-3-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate, TBTU) may be used as coupling reagent in the synthesis of macrocyclic polyamine derivatives with various length of linkers, condensation reagent in the large-scale preparation of the hematoregulatory nonapeptide (Glp-Glu-Asp)2-DAS-(Lys)2 (2,SK&F 107647), coupling reagent for peptide synthesis which best suppresses racemization during fragment condensation.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
