Peptidecouplingreagents and especially uronium/guanidinium salts have been extensively utilized in solid-phase peptidesynthesis. However, the impact of these reagents in solution phase synthesis, normally used in the formation of peptide-drug conjugates (PDCs), has not been fully explored. Herein, we identified that when guanidinium salts are used in classical peptidecoupling conditions, besides
