| Hazard Information | Back Directory | [Chemical Properties]
EDC-HCl, or 25952-53-8, is a white crystalline powder that easily deliquescent and can dissolve in both water and ethanol. It is commonly used as an activating reagent in amide synthesis to activate carboxyl groups. It can also activate phosphate groups, cross-link proteins and nucleic acids, and produce immunocouplers. EDC-HCl is commonly applied in the pH range of 4.0-6.0 and is often used in conjunction with N-Hydroxysuccinimide (NHS) or N-Hydroxysulfosuccinimide sodium salt to improve coupling efficiency. | [Uses]
1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride 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.
| [Application]
1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride is water-soluble carbodiimide, widely used for peptide coupling.
N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride has been used for the formation of FND (fluorescent nanodiamonds)-transferrin bioconjugates.
It has been used for crosslinking polyethylenimine to gold particles.
It has been used as a carbodiimide linkage agent for coating of carboxylated polystyrene beads with biotinylated BSA (bovine serum albumin). | [General Description]
EDC hydrochloride(25952-53-8) is a water-soluble derivative of carbodiimide useful for conjugating haptens to proteins and polypeptides. Used to modify NMDA receptors and as a condensing agent in peptide synthesis. The major advantage of EDAC coupling is the easy removal of excess reagent and the corresponding urea by washing with dilute acid or water. Carbodiimides catalyze the formation of amide bonds, carboxylic acids, and amines by activating the carboxylate to form an O-acylurea. This intermediate can be attacked by an amine directly to form an amide. EDAC is released as a soluble urea derivative. | [Flammability and Explosibility]
Flammable | [Biochem/physiol Actions]
N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide is a water soluble condensing reagent. EDAC is generally utilized as a carboxyl activating agent for amide bonding with primary amines. Additionally, it reacts with phosphate groups. It has been utilized in peptide synthesis, crosslinking proteins to nucleic acids as well as preparation of immunoconjugates. | [Synthesis]
1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride can be used for the synthesis of amides. It is used as a coupling agent in the synthesis of esters from carboxylic acids using dimethylaminopyridine as the catalyst. | [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.
