Methanesulfonyl fluoride, also known as fluoro methanesulfonyl, is a chemical compound with the formula CH3SO2F. It is a colorless, volatile, and highly toxic liquid that is soluble in water and organic solvents. Methanesulfonyl fluoride, fluoro- is primarily used as a fluorinating agent in organic synthesis, particularly in the preparation of fluorinated compounds. Methanesulfonyl fluoride is also known for its ability to alkylate or acylate amines, making it a valuable reagent in the synthesis of various pharmaceuticals and agrochemicals. Due to its hazardous nature, it is essential to handle this chemical with extreme care and proper safety measures.

1426-07-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1426-07-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,2 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1426-07:
(6*1)+(5*4)+(4*2)+(3*6)+(2*0)+(1*7)=59
59 % 10 = 9
So 1426-07-9 is a valid CAS Registry Number.

Development of direct fluorination technology for application to materials for lithium battery

Kobayashi, Masafumi,Inoguchi, Tetsuya,Iida, Takashi,Tanioka, Takashi,Kumase, Hiroshi,Fukai, Yasushi

, p. 105 - 110 (2003)

Direct fluorination of 1,3-dioxolan-2-one with elemental fluorine was successfully carried out to provide 4-fluoro-1,3-dioxolan-2-one, which was expected as an additive for lithium ion secondary battery. 4-Fluoro-1,3-dioxolan-2-one was also further fluorinated with elemental fluorine to give three isomers of difluoro derivatives by the same methodology. Another topic is the preparation of trifluoromethanesulfonyl fluoride, an intermediate of lithium battery electrolyte, by the reaction of methanesulfonyl fluoride with elemental fluorine. The use of perfluoro-2-methylpentane as a solvent gave satisfactory selectivity of trifluoromethanesulfonyl fluoride.
