Methylsulfonyl, also known as methanesulfonyl, is a chemical functional group with the formula CH3SO2. It is derived from methane by replacing one hydrogen atom with a sulfonyl group (SO2). Methylsulfonyl compounds are widely used in various applications, including pharmaceuticals, agrochemicals, and organic synthesis. These compounds are known for their stability, reactivity, and ability to form strong bonds with other molecules. They can act as electrophilic reagents, participating in various chemical reactions such as nucleophilic substitution, elimination, and addition reactions. Methylsulfonyl compounds are also used as protecting groups in organic synthesis, helping to prevent unwanted side reactions and facilitating the formation of desired products. Overall, the methylsulfonyl group plays a significant role in the field of chemistry due to its unique properties and diverse applications.

4853-80-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4853-80-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,5 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4853-80:
(6*4)+(5*8)+(4*5)+(3*3)+(2*8)+(1*0)=109
109 % 10 = 9
So 4853-80-9 is a valid CAS Registry Number.

Oxidation of Sulfur Dioxide by Methylperoxy Radicals

Kan, Charles S.,Calvert, Jack G.,Shaw, John H.

, p. 1126 - 1132 (2007/10/02)

This study was made to resolve the apparent discrepancy between the finite rate constants observed for the CH3O2 reaction with SO2 in high-intensity flash photolysis and near zero values observed recently by us and others for this reaction in NO-free, CH3O2-SO2 experiments at low intensity.
