''N'',''N′''-Diisopropylcarbodiimide is a

carbodiimide 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 synthesi ...

peptide synthesis In organic chemistry, peptide synthesis is the production of peptides, compounds where multiple amino acids are linked via amide bonds, also known as peptide bonds. Peptides are chemically synthesized by the condensation reaction of the carboxyl ...

. 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 solvent (s) (from the Latin '' solvō'', "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for p ...
