Application


  • Synthesis of phospho-urodilatin by combination of global phosphorylation with the segment coupling approach.: This research focuses on the synthesis of phospho-urodilatin, demonstrating the effectiveness of TBTU as a coupling reagent in segment coupling strategies for peptide synthesis (Mostafavi et al., 1996).

  • Effect of tertiary amine on the carbodiimide-mediated peptide synthesis.: The study investigates the impact of tertiary amines on carbodiimide-mediated peptide synthesis, highlighting the role of TBTU in enhancing peptide coupling efficiency (Beyermann et al., 1991).
