85211-95-6 Usage
General Description
1-(n-perfluoropentane)-1,2,2-trifluoro-1,2-ethansultone is a chemical compound that contains perfluoropentane, a highly fluorinated alkane, and ethansultone, a sulfonating agent. 1-(n-perfluoropentane)-1,2,2-trifluoro-1,2-ethansultone is used in the synthesis of perfluorinated compounds, which have a wide range of industrial applications including in refrigerants, electronics, and pharmaceuticals. Perfluorinated compounds are known for their stability and resistance to heat, chemicals, and biological degradation, making them valuable in various industries. However, the use of perfluorinated compounds has raised environmental and health concerns due to their persistence and potential toxicity. Therefore, the production and use of 1-(n-perfluoropentane)-1,2,2-trifluoro-1,2-ethansultone and similar compounds should be carefully regulated to minimize their impact on human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 85211-95-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,2,1 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 85211-95:
(7*8)+(6*5)+(5*2)+(4*1)+(3*1)+(2*9)+(1*5)=126
126 % 10 = 6
So 85211-95-6 is a valid CAS Registry Number.

Fluorosulfonation. Insertion of Sulfur Trioxide into Allylic C-F Bonds
Krespan, Carl G.,Dixon, David A.
, p. 4460 - 4466 (1986)
Insertion of sulfur trioxide into allylic C-F bonds of both terminal and internal fluoro olefins is shown to form the most stable olefinic products.A mechanism involving fluoroallyl cations as intermediates is proposed.State-of-the-art ab initio calculations of the ground-state energies for two isomeric unsaturated fluoro ethers establish the slightly greater stability (5.7 kcal/mol) of a vinyl ether over the corresponding fluoro olefin.A description of the optimized geometries of these molecules is also presented.
