13746-89-9 Usage
Physical Properties
The pentahydrate is a white crystalline solid; very hygroscopic; refractive index 1.60; very soluble in water; the aqueous solution acidic; soluble in alcohol.
Uses
Zirconium nitrate is used as a preservative, as an analytical standard for zirconium, and in making zirconium salts.
Preparation
Zirconium nitrate is prepared by reacting nitric acid with zirconium oxide:
ZrO2 + 4HNO3 → Zr(NO3)4 + 2H2O
The compound is crystallized as pentahydrate following evaporation to dryness.
Chemical Properties
white, very hygroscopic crystal(s) [MER06]
General Description
Zirconium(IV) nitrate is a white crystalline solid. Zirconium(IV) nitrate is soluble in water. Zirconium(IV) nitrate is noncombustible, but Zirconium(IV) nitrate will accelerate the burning of combustible materials. If large quantities are involved in a fire or the combustible material is finely divided, an explosion may result. Prolonged exposure to fire or heat may result in an explosion. Toxic oxides of nitrogen are produced in fires involving Zirconium(IV) nitrate. Zirconium(IV) nitrate is used as a preservative.
Reactivity Profile
Mixtures of metal/nonmetal nitrates, such as Zirconium(IV) nitrate, with alkyl esters may explode owing to the formation of alkyl nitrates; mixtures a nitrate with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979. p. 108-109]. Dissolves in water to give an acid solution.
Health Hazard
Has only a mild pharmacological action. Inhalation of dust may irritate nose and throat. Contact with eyes or skin causes irritation.
Safety Profile
Moderately toxic by
inhalation and ingestion. A powerful
oxiQzer. When heated to decomposition it
emits toxic fumes of NOx. See also

Check Digit Verification of cas no
The CAS Registry Mumber 13746-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,4 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13746-89:
(7*1)+(6*3)+(5*7)+(4*4)+(3*6)+(2*8)+(1*9)=119
119 % 10 = 9
So 13746-89-9 is a valid CAS Registry Number.
