Applicazioni

N,N'-Diisopropylcarbodiimide is used as a reagent in synthetic organic chemistry. It serves as a chemical intermediate and as a stabilizer for Sarin (chemical weapon). It is also used in the synthesis of peptide and nucleic acid. Further, it is used as an antineoplastic and involved in the treatment of malignant melanoma and sarcomas. In addition to this, it is used in the synthesis of acid anhydride, aldehyde, ketone and isocyanate.

Note

Moisture sensitive. Store in a cool place Incompatible with oxidizing agents and acids.

Letteratura

Reagent for peptide coupling: J. Org. Chem., 44, 5000 (1979). Has the advantage over N,N'-Dicyclohexyl­carbodiimide, A10973 in solid phase peptide syntheses that the urea by-product is more soluble in organic solvents and hence more readily separated from the polymer support. For peptide reagents, see Appendix 6.
