7790-47-8 Usage
Chemical Properties
Brown powder
Uses
Tin(IV) iodide is used in the preparation of tin(IV) oxide and tin(II) oxide. It reacts with hydroiodic acid to get rare tin hexaiodide. It forms tetraiodobis triphenylphosphine tin complexes by reacting with triphenylphosphine, which finds application in toothpaste formulation. Further, it acts as analytical reagents and also used in organic synthesis.
Safety Profile
Poison by intravenous
route. Strong reaction with N02Cl, (K+ S),
(Na + S). When heated to decomposition it
emits toxic fumes of I-. See also TIN
COMPOUNDS and IODIDES.
Purification Methods
It is recrystallised from anhydrous CHCl3, dry it under vacuum and store it in a vacuum desiccator. It sublimes at 180o.
Check Digit Verification of cas no
The CAS Registry Mumber 7790-47-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,9 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7790-47:
(6*7)+(5*7)+(4*9)+(3*0)+(2*4)+(1*7)=128
128 % 10 = 8
So 7790-47-8 is a valid CAS Registry Number.
