Uses
Used in Analytical Chemistry:
Potassium pyrosulfate is used as an acid flux in analysis for the conversion of hemicellulose into reducing sugars such as xylose and galactose by mechanocatalysis. It aids in the breakdown and analysis of complex organic compounds.
Used in Organic Synthesis:
In the field of organic synthesis, potassium pyrosulfate is used as a salt catalyst for the preparation of diacylbenzenes via Pd-catalyzed decarboxylative acylation of aromatic ketones with oxocarboxylic acids. It facilitates the formation of desired products by promoting the reaction between the reactants.
Used in Oxidation Reactions:
Potassium pyrosulfate is used as an oxidant for the preparation of monosubstituted triazoles from aryl azides and propargyl alcohol using Ag2O as a catalyst. It helps in the oxidation process, leading to the formation of the desired triazole compounds.
Used in Silica-supported Catalysts:
Potassium disulfite supported on silica may be used for the synthesis of ethyl pyruvate. The silica-supported catalyst enhances the reactivity and selectivity of the reaction, making it more efficient and practical for industrial applications.

Check Digit Verification of cas no
The CAS Registry Mumber 7790-62-7 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, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7790-62:
(6*7)+(5*7)+(4*9)+(3*0)+(2*6)+(1*2)=127
127 % 10 = 7
So 7790-62-7 is a valid CAS Registry Number.
