506-68-3 Usage

Uses

Reaction with C60Ph5Cl produces a novel phenylated isoquinolino[3′,4′:1,2][60]fullerene.1

Uses

Reagent for the synthesis of cyanamides.

Fire Hazard

Cyanogen bromide is not combustible itself, but impure Cyanogen bromide decomposes rapidly and tends to explode. A violent reaction may take place on contact with large quantities of acid. Vapors are highly irritating. When material is heated to decomposition, Cyanogen bromide emits very toxic fumes of cyanide and bromide. Avoid water, acids. Avoid physical damage, contact with acids or water, and store away from a location where water may be needed for fire control.

Reactivity Profile

Cyanogen bromide is not combustible itself, but impure Cyanogen bromide decomposes rapidly and tends to explode. A violent reaction may take place on contact with large quantities of acid. Avoid physical damage, contact with acids or water, and store away from a location where water may be needed for fire control. [EPA, 1998]. Benzene and cyanogen halides yield HCl as a byproduct (Hagedorn, F. H. Gelbke, and Federal Republic of Germany. 2002. Nitriles. In Ullman Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA.).

Chemical Properties

white crystalline solid

Purification Methods

All operations with this substance should be performed in a very efficient fume cupboard-it is very POISONOUS and should be handled in small amounts. Fresh commercial material is satisfactory for nearly all purposes and does not need to be purified. It is a white crystalline solid with a strong cyanide odour. If it is reddish in colour and partly liquid or paste-like, then it is too far gone to be purified, and fresh material should be sought. It can be purified by distillation using small amounts at a time, and using a short wide-bore condenser because it readily solidifies to a crystalline white solid which may clog the condenser. An appropriate gas mask should be used when transferring the molten solid from one container to another, and the operation should be done in an efficient fume cupboard. The melting point (m 49-51o) should be measured in a sealed tube. [Hartman & Dreger Org Synth Coll Vol II 150 1948.]

Health Hazard

Super toxic; probable oral lethal dose in humans is less than 5 mg/kg or a taste (less than 7 drops) for a 70 kg (150 lb.) person. Vapors are highly irritant and very poisonous. Individuals with chronic diseases of the kidneys, respiratory tract, skin, or thyroid are at greater risk of developing toxic cyanide effects.

Air & Water Reactions

Cyanogen bromide is slightly soluble in water. Cyanogen bromide is gradually decomposed by water and very rapidly by acids to give off hydrogen bromide, a poison gas.

General Description

Cyanogen bromide is a colorless to white crystalline solid with a penetrating odor. Cyanogen bromide is slightly soluble in water. Cyanogen bromide is gradually decomposed by water and very rapidly by acids to give off hydrogen bromide, a flammable and poisonous gas. Contamination with many materials can cause rapid decomposition of the material. Cyanogen bromide is toxic by inhalation of its vapors or by the hydrogen cyanide from decomposition or by ingestion. Toxic oxides of nitrogen are produced in fire involving Cyanogen bromide. Cyanogen bromide is used in gold extraction, to make other chemicals, and as a fumigant.
