| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

The common method of peptide synthesis is not feasible for industry use due to its poor yields. CDI, a new peptide forming reagent, is applied recently as a more direct agent for the formation of acyl-imidazoles. [1]
In vitro: CDI can be prepared straightforwardly by the reaction of phosgene with four equivalents of imidazole under anhydrous conditions. It served as a convenient reagent for peptide synthesis since its side products, carbon dioxide and imidazole, were safe. Moreover, the carbon dioxide evolution was suggested to provide driving force for the peptide synthesis. A typical peptide-formation reaction was started by dissolving 0.010 mole acylamino acid in 10 ml tetrahydrofuran (THF), and after this, the evolution of carbon dioxide could be immediately observed. An hour later, the required amino acid or peptide ester was added with an amount of 0.010 molar. The reaction would be last for 15 min, but longer standing is probably beneficial. The formed peptide was then purified by wiping off the solvent under vacuum followed by washing the residue with acid, saturated bicarbonate and finally water.[1]
In vivo: So far, no in vivo data has been reported.
Clinical trial: So far, no clinical trial has been conducted.

1,1'-Carbonyldiimidazole (CDI) Mediated Coupling and Cyclization To Generate [1,2,4]Triazolo[4,3-a]pyridines.[Pubmed:26808327]
Org Lett. 2016 Feb 5;18(3):560-3.
An operationally efficient CDI mediated tandem coupling and cyclization reaction to generate [1,2,4]triazolo[4,3-a]pyridines has been reported. The reaction conditions and scope were investigated, and the methodology was demonstrated in batch mode as well as in a continuous process.
