General description

DIC is an abbreviated form of N,N′-diisopropylcarbodiimide. It plays a role in the cyclization of N-(β-hydroxy)amides to form 2-oxazolines.

Application

Coupling reagent for peptide syntheses.
DIC (N,N′-Diisopropylcarbodiimide) has been used in combination with 1-hydroxy-7-azabenzotriazole (HOAt) for the coupling of amino acid with N-allylglycine to form N-allylpeptide.
Alternative to dicyclohexylcarbodiimide in peptide synthesis.
