N,N'-Diisopropylcarbodiimide

N,N′-Diisopropylcarbodiimide is a carbodiimide used in peptide synthesis. As a liquid, it is easier to handle than the commonly used N,N′-dicyclohexylcarbodiimide, a waxy solid. In addition, N,N′-diisopropylurea, its byproduct in many chemical reactions, is soluble in most organic solvents, a property that facilitates work-up.
