General Description
Perchloryl fluoride is a colorless, non corrosive gas with a characteristic sweet odor. Contact with the material may cause irritation to skin, eyes, and mucous membranes. Perchloryl fluoride is very toxic by inhalation and skin absorption. Under prolonged exposure to fire or intense heat the containers may violently rupture and rocket.
Air & Water Reactions
Slightly soluble in water.
Reactivity Profile
Perchloryl fluoride is a propellant; a powerful oxidant. Perchloryl fluoride ignites upon contact with alcohols, amines, ammonia, beryllium alkyls, boranes, dicyanogen, hydrazines, hydrocarbons, hydrogen, nitroalkanes, powdered metals, silanes, or thiols [Bretherick 1979. p.174].
Safety Profile
A poison gas which forms methemoglobin in the body and destroys red cells causing anemia, anorexia, and cyanosis. Recovery is said to be rapid, leaving no permanent physiological damage. Can be absorbed through the skin. Its odor can be detected as low as 10 ppm although this cannot be relied upon as an indication of toxic concentration in air. While nonflammable, it supports combustion. It is a powerful oxidzer. Moderately explosive. Potentially explosive reactions with combustible gases or vapors. benzene + aluminum trichloride, benzocyclobutene + butyllithium + potassium tert-butoxide, calcium acetylide, potassium cyanide, potassium thiocyanate, sodium iochde, charcoal, ethyl-4-fluorobenzoylacetate, hydrocarbons, hydrogen sulfide, nitrogen oxide, sulfur dichloride, vinylidene chloride, 3a-hydroxy-5p-androstane-1 1,17-di0ne-l 7hydrazone, lithiated compounds, 2lithio (dimet hy laminomethyl)f erroxene, methyl-2-bromo-5,5-ethylene dioxy(2,2,1)bicycloheptane-7-carboxylate, aliphatic heterocyclic amines, sodium methoxide + methanol, vinylidene chloride. Reacts to form explosive products with nitrogenous bases (e.g., isopropylamine, isobutylamine, aniline, phenyl hydrazine, 1,2-diphenyl hydrazine), sawdust, lampblack. Violent reaction with finely dwided organic materials. A fluorinating agent in chemical synthesis, and an oxidant in rocket fuel. When heated to decomposition it emits toxic fumes of Fand Cl-.

Shipping
UN3083 Perchloryl fluoride, Hazard Class: 2.3; Labels: 2.3-Poisonous gas, 5.1-Oxidizer, Inhalation Hazard Zone B. UN3157 Liquefied gas, oxidizing, n.o.s., Hazard Class: 2.2; Labels: 2.2-Non-flammable compressed gas, 5.1-Oxidizer, Technical Name Required. Cylinders must be transported in a secure upright position, in a well-ventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner.
Incompatibilities
A strong oxidizing gas. Violent reaction with benzene, calcium hydride; combustibles, olefins, strong bases; sulfur, sulfuric acid; amines, reducing agents; alcohols. Contact with carbonaceous materials (such as charcoal) or finely divided metals (such as powdered magnesium and aluminum, zinc) are a fire and explosion hazard. Attacks some plastics, rubber, and coatings
Waste Disposal
Return refillable compressed gas cylinders to supplier. Incineration together with flammable solvent in furnace equipped with afterburner and scrubber.
Check Digit Verification of cas no
The CAS Registry Mumber 7616-94-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,1 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7616-94:
(6*7)+(5*6)+(4*1)+(3*6)+(2*9)+(1*4)=116
116 % 10 = 6
So 7616-94-6 is a valid CAS Registry Number.

On the reaction of 4-substituted trimethyltin aromatics with perchlorylfluoride
Hiller, Achim,Patt, J?rg T.,Steinbach, J?rg
, p. 3737 - 3742 (2007/10/03)
To evaluate the suitability of [18F]perchorylfluoride [18F]FClO3 as an electrophilic fluorination agent for the preparation of radiopharmaceuticals, the reactivity non-radioactive FClO3 towards 4-substituted trimethyltin aromatic compounds was studied. Contrary to the expectation, an electrophilic fluorination of the aromatic nucleus did not occur. The reaction of perchlorylfluoride with aromatic trimethylstannyl compounds resulted in the formation of trimethyltin fluoride and the respective destannylated aromatics in variable yields.
