In organic chemistry, a carbodiimide (systematic IUPAC name: methanediimine ) is a functional group with the formula RN=C=NR. They are exclusively synthetic. A well known carbodiimide is dicyclohexylcarbodiimide, which is used in peptide synthesis. Dialkylcarbodiimides are stable. Some diaryl derivatives tend to convert to dimers and polymers upon standing at room temperature, though thi… WebMay 20, 2024 · Quench EDC Coupling Reaction.
