Dicyclohexylcarbodiimide Chemical Properties,Uses,Production

Chemical Properties

Colorless solid

Chemical Properties

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

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.

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

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.

Definition

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

Uses

In the synthesis of peptides.

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.

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

Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victimingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy

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. Biochemical Preparations 10, 122 1963, Schmidt & Seefelder Justus Liebigs Ann Chem 571 83 1951, Schmidt et al. Justus Liebigs Ann Chem 612 11 1958, Beilstein 12 IV 72.]

Incompatibilities

Dust may for explosive mixture with air. Reacts with steam and water. N,N0 - Dicyclohexylcarbodiimide is an amine/imide: contact with strong oxidizers may cause fire and explosions. Incompatible with acids, strong bases, strong reducing agents (may form flammable gasses); azo and diazo compounds (may form toxic gases); chlorinated hydrocarbons; nitro compounds. Contact with mixture of acetic acid 1 dinitrogen trioxide may cause explosion. The combustion of amide compounds generate nitrogen oxides (NOx). In the presence of moisture, may attack metals and plastics.

Waste Disposal

Whatever cannot be saved for recovery or recycling should be managed in an appropriate and approved waste facility. Although not a listed RCRA hazardous waste, this material may exhibit one or more characteristics of a hazardous waste and require appropriate analysis to determine specific disposal requirements. Processing, use or contamination of this product may change the waste management options. State and local disposal regulations may differ from federal disposal regulations. Dispose of container and unused contents in accordance with federal, state and local requirements
