118-76-3 Usage
General Description
Rhodizonic acid dihydrate is a chemical compound with the formula H4C6N4O6. It is a highly toxic and reactive compound that is used primarily as a reagent in chemical analysis, particularly for the detection of metals such as lead and silver. It is a white crystalline solid that is soluble in water and other polar solvents. Rhodizonic acid dihydrate is known to be a potent oxidizing agent and should be handled with extreme caution due to its toxic and corrosive nature. It has limited industrial use and is primarily used in laboratory settings for analytical purposes.
Check Digit Verification of cas no
The CAS Registry Mumber 118-76-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 118-76:
(5*1)+(4*1)+(3*8)+(2*7)+(1*6)=53
53 % 10 = 3
So 118-76-3 is a valid CAS Registry Number.

Reversible solid-state interconversion of rhodizonic acid H2C6O6 into H6C6O8 and the solid-state structure of the rhodizonate dianion C6O62- (aromatic or non-aromatic?)

Anhydrous rhodizonic acid H2C6O6 is obtained by (fully reversible) thermal dehydration of solid 2,3,5,5,6,6-hexahydroxycyclohex-2-ene-1,4-dione, H6C6O8, commonly known as rhodizonic acid dihydrate. Treatment of H6C6O8 with RbOH yields crystals of Rb2C6O6; the oxocarbon dianion C6O62- is shown to possess a flat, benzene-type structure, with C-C bonds shorter than expected for a (non-aromatic) ketonic-type structure.
