1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride Usage And Synthesis


Chemical Properties White crystalline powder


Uses It is being used for the synthesis of amides. EDC.HCl is also used as a coupling agent in the preparation of esters from carboxylic acids using dimethylaminopyridine as the catalyst. It is water-soluble carbodiimide, widely used for peptide coupling.


Uses An enzyme inhibitor


Purification Methods It is an excellent H2O-soluble peptide coupling reagent. It is purified by dissolving (ca 1g) in CH2Cl2 (10mL) at room temperature and then add dry Et2O (~110mL) dropwise and the crystals that separate are collected, washed with dry Et2O, recrystallised from CH2Cl2/Et2O and dried in a vacuum over P2O5. It is important to work in a dry atmosphere or work rapidly and then dry the solid as soon as possible. The material is moderately hygroscopic, but once it becomes wet it reacts slowly with H2O. Store it away from moisture at -20o to slow down the hydrolysis process. The free base has b 47-48o/0.27mm, 53-54o/0.6mm, n 1.4582. The methiodide is recrystallised from CHCl3/EtOAc, the crystals are filtered off, washed with dry Et2O, recrystallised from CHCl3/Et2O, and dried in vacuo over P2O5, m 93-95o, 94-95o. [Sheehan et al.
