beige to light brown or light pink crystalline

Generally for destroying all lower forms of life. In taxidermy for preserving insects, butterflies, etc.

White needles with a very pungent odor. Used in taxidermists' preservatives and generally for destroying all lower forms of life. Toxic by inhalation or ingestion.

Water soluble.

Phosphorus(molten) plus CYANOGEN IODIDE reacts with incandescence to produce phosphorus iodide, [NFPA 491M, 1991]. 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.).

Causes convulsions, paralysis and death from respiratory failure. Highly toxic; strong irritant to eyes and skin. (Non-Specific -- Cyanide or Cyanide Mixture, Dry): Poisonous, may be fatal if swallowed or absorbed through skin. Contact may cause burns to the skin and eyes. Fire may produce irritating or poisonous gases.

When heated to decomposition, CYANOGEN IODIDE emits very toxic fumes of nitrogen oxides, cyanide, and iodide. Avoid phosphorus.

Reacts slowly with water releasing hydrogen cyanide. Incompatible with phosphorus (molten); reacts with incandescence to produce phosphorus iodide . Contact with alcohols, acids, ammonia, carbon dioxide or alkaline material and bases produces toxic gases including hydrogen cyanide. Incompatible with nitriles.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek Medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immedi- ately with soap and water. Seek Medical attention immedi- ately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precau- tions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Effects may be delayed; keep victim under observa- tion. Use amyl nitrate capsules if symptoms develop. All area employees should be trained regularly in emergency measures for cyanide poisoning and in CPR. A cyanide antidote kit should be kept in the immediate work area and must be rapidly available. Kit ingredients should be replaced every 1 2 years to ensure freshness. Persons trained in the use of this kit; oxygen use, and CPR must be quickly available.

Cyanogen iodide is a combustible, white crystalline solid with a very pungent odor. Molecularweight=152.92; Freezing/Melting point=146.5℃. HazardIdentification (based on NFPA-704 M Rating System):Health 4, Flammability 0, Reactivity . Soluble in water;slow reaction.

This compound is POISONOUS, and the precautions for cyanogen bromide (above) apply here. The reagent (ca 5.9g) is dissolved in boiling CHCl3 (15mL), filtered through a plug of glass wool into a 25mL Erlenmeyer flask. Cool to room temperature for 15minutes, then place it in an ice-salt bath and cool to -10o. This cooling causes a small aqueous layer to separate as ice. The ice is filtered with the CNI, but melts on the filter and is also removed with the CHCl3 used as washing liquid. The CNI which is collected on a sintered glass funnel is washed 3x with CHCl3 (1.5mL at 0o) and freed from last traces of solvent by placing it on a watch glass and exposing it to the atmosphere in a good fume cupboard at room temperature for 1hour to give colourless needles (ca 4.5g), m 146-147o (sealed capillary totally immersed in the oil bath). The yield depends slightly on the rapidity of the operation; in this way loss by sublimation can be minimised. If desired, it can be sublimed under reduced pressure at temperatures at which CNI is only slowly decomposed into I2 and (CN)2. The vacuum will need to be renewed constantly due to the volatility of CNI. [Bak & Hillebert Org Synth Coll Vol IV 207 1963.]

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with cyanogeniodide you should be trained on its proper handlingand storage. Store in tightly closed containers in a cool,well-ventilated area. Refrigerate at (approx.) 4℃. Metal

A suitable method for destroying cyanogen iodide may consist of treatment with caustic soda, followed by adding sodium hypochlorite (laundry bleach) to oxidize the cyanide to nontoxic cyanate.
