506-78-5 cyanogen iodide

No exposure limit is set. However, on the basis of the exposure limits of related compounds a ceiling limit of 0.5 ppm (2 mg/m ) is recommended. 

Inhalation of oxygen and amyl nitrite may combat cyanogen bromide poisoning. 

Cyanogen bromide can be destroyed by slowly adding to it an aqueous solution of caustic soda followed by an addition of excess of laundry bleach. Nontoxic sodium thiocyanate and unreacted bleach are drained down with large volumes of water. 

Cyanogen bromide is used in taxidermy for preserving insects, butterflies, and so on (Merck 1989). 

White crystalline solid highly pungent smell acrid taste mp 147°C (296.6°F) soluble in water, alcohol, and ether.

Thiadiazinotriazolopyrimidines can be prepared in several ways from the hydrazine-substituted thiadiazino-pyrimidine 186. Reaction with carbon disulfide gives the thione 187 reaction with either anhydrides or orthoformates with sulfuric acid gives the substituted triazoles 188, and reaction with cyanogen iodide gives the aminotriazole 189 (Scheme 47) <2004HC0335>.

We obtained diethyl phosphorocyanidate (V) in only small yield by the action of potassium cyanide on the corresponding phosphorochloridate. We were able to prepare it,6 however, by the action of cyanogen iodide on the phosphite. This is apparently a modified Arbusov reaction ...

Besides molecular iodine, X-iodosuccinimide, 86 cyanogen iodide, 87 and diacetoxy-phenyliodine 88 have been proposed as alternative sources of the iodonium ion. 

Caution Cyanogen iodide is relatively volatile and highly toxic. Therefore, these operations should be conducted in a good hood. 

In this way sodium iodide, soluble in the solution of cyanogen iodide in ether [complex formation of NaI2(CN)], is removed. This complex is avoided in the procedure by Ketelaar and Kruyer 2 in which chlorine is used. The method adopted here is faster and simpler and gives almost the same yield of purified cyanogen iodide. 

Determinations of the melting point of cyanogen iodide must be made using a sealed capillary which is kept totally immersed in the heating bath. 

When the chloroform solution is cooled, a small aqueous layer is observed which finally separates as ice. The ice is filtered with cyanogen iodide but melts on the filter plate and is removed with the chloroform used as washing liquid.
