Thermo Scientific™ 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride, 98+%,

1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride is used as a carboxyl activating agent. It is used in peptide synthesis, 3'-amino-3'-deoxyadenosine-5'-di- and triphosphates and in the preparation of antibodies like immunoconjugates. It plays a vital role for immobilization of large biomolecules in association with N-hydroxysuccinimide. It is also used in the acylation of phosphoranes.

Water-soluble carbodiimide, widely used for peptide coupling (see Appendix 6), with the major advantage that excess reagent and the urea by-product can be easily removed by washing with dilute acid or water: J. Org. Chem., 26, 2525 (1961); J. Am. Chem. Soc., 87, 2492 (1965). For discussion of the mechanism of peptide coupling with this reagent, see: J. Am. Chem. Soc., 103, 7090 (1981).
