Uses
Used in Organic Synthesis:Methanesulfonic anhydride is used as a reagent for the acetylation of alcohols and amines, facilitating the formation of esters and amides, respectively. Its strong acidity enhances the reactivity of these processes, making it a valuable component in organic synthesis.
Used in Pharmaceutical Production:
In the pharmaceutical industry, methanesulfonic anhydride is utilized as a key intermediate in the synthesis of various drugs. Its ability to acylate functional groups contributes to the development of new pharmaceutical compounds with specific therapeutic properties.
Used in Agrochemical Production:
Methanesulfonic anhydride also finds application in the agrochemical sector, where it is employed in the synthesis of pesticides and other crop protection agents. Its reactivity aids in the creation of compounds that can effectively protect crops from pests and diseases.
Used as a Dehydrating Agent:
Due to its strong dehydrating properties, methanesulfonic anhydride is used to remove water from reactions, promoting the formation of desired products and improving the efficiency of chemical processes. This application is particularly useful in reactions where water is a byproduct, ensuring that the reaction proceeds to completion.
Check Digit Verification of cas no
The CAS Registry Mumber 370071-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,0,0,7 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.Calculate Digit Verification of CAS Registry Number 370071-69:
(8*3)+(7*7)+(6*0)+(5*0)+(4*7)+(3*1)+(2*6)+(1*9)=125
125 % 10 = 5
So 370071-69-5 is a valid CAS Registry Number.
