21111-84-2 Usage
General Description
Lithium periodate is a chemical compound with the formula LiIO4. It is a strong oxidizing agent and is commonly used in organic synthesis as a reagent for the selective oxidation of alcohols to aldehydes or ketones. It is also used in the preparation of iodine compounds. Lithium periodate is a white crystalline solid that is stable at room temperature and can be stored for long periods without decomposition. However, it should be handled with care as it is corrosive and may cause skin and eye irritation upon contact. Overall, lithium periodate is a versatile chemical with various applications in the field of organic chemistry.
Check Digit Verification of cas no
The CAS Registry Mumber 21111-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,1 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21111-84:
(7*2)+(6*1)+(5*1)+(4*1)+(3*1)+(2*8)+(1*4)=52
52 % 10 = 2
So 21111-84-2 is a valid CAS Registry Number.

Li2H4I2O10, the first tetrahydrogendimesoperiodate
Jansen, Martin,Mueller, Ralph
, p. 1901 - 1906 (1996)
Li2H4I2O10 has been obtained as an intermediate during the dehydration of LiH4IO6 · H2O to LiIO4, for the first time. According to the results of an X-ray structure determination (monoclinic, P21/n, a = 533.98(4), b = 471.85(4), c = 1431.48(10) pm, β = 91.614(7)°, Z = 2, 726 diffractometer data, R = 0.056), Li2H4I2O10 contains the previously unknown tetrahydrogendimesoperiodate ion H4I2O102-, consisting of two edge-shared IO6 octahedra. They are connected with LiO6 octahedra via common edges and vertices. The crystals are non-merohedrally twinned along (100). Johann Ambrosius Barth 1996.
