Pentafluoroethyl fluorosulfate (PFES) is a highly reactive and potent chemical compound with the formula C2F6O2S. It is an alkylating agent and a fluorosulfate ester, known for its ability to alkylate and fluorosulfonate nucleophiles, making it a valuable reagent in organic synthesis. PFES is characterized by its strong electrophilic properties, which arise from the presence of the pentafluoroethyl group and the fluorosulfate group. pentafluoroethyl fluorosulfate is also recognized for its potential use in the synthesis of certain pharmaceuticals and agrochemicals, as well as its potential applications in materials science. However, due to its reactivity, it requires careful handling and is typically used in controlled laboratory settings.

Check Digit Verification of cas no

The CAS Registry Mumber 1479-51-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,7 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1479-51:
(6*1)+(5*4)+(4*7)+(3*9)+(2*5)+(1*1)=92
92 % 10 = 2
So 1479-51-2 is a valid CAS Registry Number.

GEMINAL FLUOROSULFONYLOXY FLUOROSULFONYL COMPOUNDS

Eleev, A.F.,Sokol'skii, G.A.

, p. 846 - 848 (2007/10/02)

Previously unknown compounds containing fluorosulfonyl and fluorosulfonyloxy groups at the same carbon atom were obtained by the reaction of peroxydisulfuryl fluoride with α-H-polyfluoroethanesulfonyl fluorides.The reactivity of the compounds toward Lewis acids and bases was evaluated.
