Dicyclohexylcarbodiimide Chemical Properties,Usage,Production

Description

Dicydohexyl carbodiimide is used in peptide chemistry as a coupling reagent. It is both an irritant and a sensitizer, and caused contact dermatitis in pharmacists and chemists.

Chemical Properties

N,N0 -Dicyclohexylcarbodiimide (DCC) is a white crystalline solid. Odor is sweet and heavy.

Chemical Properties

Colorless solid

Uses

dicyclohexylcarbodiimide is used as a dehydrating agent at room temperature after a short reaction time, after the reaction product is dicyclohexylurea. the product is very small solubility in an organic solvent, so that easy separation of the reaction product.

Uses

N,N'-Dicyclohexylcarbodiimide is a carbodiimide used to couple amino acids during peptide synthesis. N,N'-Dicyclohexylcarbodiimide is used as a dehydrating agent for the preparation of amides, ketones , nitriles as well as in the inversion and esterification of secondary alcohols.

Uses

In the synthesis of peptides.

Uses

This product is mainly used in amikacin, glutathione dehydrants, as well as in synthesis of acid anhydride, aldehyde, ketone, isocyanate; when it is used as dehydrating condensing agent, it reacts to dicyclohexylurea through short-time reaction under normal temperature. This product can also be used in synthesis of peptide and nucleic acid. It is easy to use this product to react with compound of free carboxy and amino-group into peptide. This product is widely used in medical, health, make-up and biological products, and other synthetic fields.

Preparation

A stirred mixture of N,N′-dicyclohexylurea (19.7 g), phosphorus pentoxide (100 g), sand (175 g), and pyridine (700 mL) was refluxed for 2.25 h. Stirring was no longer possible after about 30 min. The mixture was filtered and the residue was extracted with pyridine (100 mL). Pyridine was removed from the combined solutions on a flash evaporator, and the residual oil was extracted with boiling petroleum ether (bp 60–80 C°) (2 × 100 mL), and then with diethyl ether (100 mL). The combined extracts were washed with iced water (3×80 mL), dried over calcium chloride, and filtered. The solvents were removed from the filtrate under reduced pressure to give 17.4 g of an oil, which on distillation yielded 13.7 g (76%) of a clear liquid; bp 143 C° (3.5 mmHg), which solidified in the receiver; mp 34–35 C°.
Another method for producing DCC from dicyclohexylurea is a two-step process using phosphoryl chloride in dichloromethane at 40 C° for 4 h under non-basic conditions followed by removal of acidic components with aq. sodium hydroxide. This method, which gives an 89% yield of DCC, has been presented in a patent application.

Preparation

Palladium acetate (22 mg, 0.1 mmol), iodine (50 mg, 0.2 mmol), and anhydrous sodium carbonate (320 mg, 3.0 mmol) were placed in a pressure vessel. Cyclohexylamine (0.11 mL, 1.0 mmol) and cyclohexyl isocyanide (0.1 mL, 0.8 mmol) were dissolved in acetonitrile (10 mL) and this solution was added to the reaction vessel, which was then pressurized with oxygen (40 psi) and heated to 100 C° for 3 h. The initially deep-red reaction mixture turned yellow-orange; no Pd black precipitation was observed. There was no obvious reaction rate dependence on oxygen pressure. The mixture was cooled to ambient temperature, depressurized, filtered, and analyzed by GC. DCC was isolated by evaporating the solvent and residual amine, followed by vacuum distillation.
Palladium(II) complexes with a carbodiimide ligand, in which a nitrogen of the linear NbCbN moiety is bonded to the metal center, and bis(carbodiimido)palladium(II) complexes, both derived from isocyanides, have been described.

Definition

ChEBI: A carbodiimide compound having a cyclohexyl substituent on both nitrogen atoms.

General Description

White crystalline solid with a heavy sweet odor.

Air & Water Reactions

Sensitive to moisture.

Reactivity Profile

Dicyclohexylcarbodiimide is an imide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). Dicyclohexylcarbodiimide is incompatible with acids and oxidizing agents. Dicyclohexylcarbodiimide reacts with water.

Hazard

A poison by skin contact. Moderately toxic by ingestion and inhalation.

Fire Hazard

Dicyclohexylcarbodiimide is probably combustible.

Flammability and Explosibility

Not classified

Contact allergens

Used in peptide chemistry as a coupling reagent. It is both an irritant and a sensitizer and has caused contact dermatitis in pharmacists and chemists.

Potential Exposure

Laboratory reagent

First aid

Eyes: Check the victim for contact lenses andremove. Flush victim’s eyes with water or normal salinesolution for 20-30 min, lifting lower and upper eyelidsoccasionally. Remove contaminated clothing and shoes. Getmedical attention immediately. Do not put any ointments,oils, or medication in the victim’s eyes without specificinstructions from a physician. Immediately transport thevictim after flushing eyes to a hospital even if no symptoms(such as redness or irritation) develop. Skin: Immediatelyflood affected skin with water and wash for at least 15 min.Remove and isolate all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. Ifsymptoms such as redness or irritation develop, immediately call a physician. Transport the victim to a hospital fortreatment. Inhalation: Remove victim to fresh air. If notbreathing, give artificial respiration. If breathing is difficult,give oxygen. Get medical attention immediately. Ingestion:Do not induce vomiting. If the victim is conscious and notconvulsing, give large amount of water to dilute the chemical. Never give anything by mouth to an unconscious person. If symptoms (such as wheezing, coughing, shortness ofbreath, or burning in the mouth, throat, or chest) develop,call a physician. In all cases get medical attention immediately. If the victim is convulsing or unconscious, do notgive anything by mouth, ensure that the victim’s airway isopen and lay the victim on his/her side with the head lowerthan the body.

storage

Color Code—White: Corrosive or Contact Hazard;Store separately in a corrosion-resistant location. KeepDCC in a tightly closed container in a cool, dry, ventilatedarea away from sources of incompatible materials, heat,direct sunlight, moisture, or ignition; best stored under aninert atmosphere at refrigerated temperatures. Containers ofDCC may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.

Purification Methods

It is sampled as a liquid after melting in warm H2O. It is sensitive to air, and it is a potent skin irritant. It can be distilled in a vacuum and is best stored in a tightly stoppered flask in a freezer. It is very soluble in CH2Cl2 and pyridine where the reaction product with H2O, after condensation, is dicyclohexyl urea which is insoluble and can be filtered off. Alternatively dissolve it in CH2Cl2, add powdered anhydrous MgSO4, shake for 4hours, filter, evaporate and distil at 0.6mm pressure and oil bath temperature of 145o. [Bodansky et al.
