Uses
Used in Surfactant Industry:
BIS[2-(FLUOROSULFONYL)TETRAFLUOROETHYL]ETHER is used as a surfactant for its ability to reduce surface tension between liquids and solids, facilitating the mixing and interaction of substances. Its stability and resistance to chemical reactions make it a reliable component in various formulations.
Used in Refrigerant Industry:
In the refrigerant industry, BIS[2-(FLUOROSULFONYL)TETRAFLUOROETHYL]ETHER is used as a component in refrigerant blends, taking advantage of its heat resistance and electric insulating properties to enhance the performance and safety of refrigeration systems.
Used in Medical Imaging:
BIS[2-(FLUOROSULFONYL)TETRAFLUOROETHYL]ETHER is used as a contrast agent in medical imaging, particularly in fluoroscopic procedures. Its chemical properties allow for clear visualization of internal structures without interfering with the imaging process.
Used in Pharmaceuticals:
BIS[2-(FLUOROSULFONYL)TETRAFLUOROETHYL]ETHER is used as an intermediate in the synthesis of pharmaceutical compounds, leveraging its stability and reactivity to produce drugs with desired therapeutic effects.
However, it is important to note that the chemical stability of BIS[2-(FLUOROSULFONYL)TETRAFLUOROETHYL]ETHER, like other fluorochemicals, also raises environmental concerns. Their resistance to degradation can lead to accumulation in the environment, potentially causing long-term ecological impacts. As a result, the use and disposal of such compounds must be carefully managed to mitigate these risks.
Check Digit Verification of cas no
The CAS Registry Mumber 146829-79-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,8,2 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 146829-79:
(8*1)+(7*4)+(6*6)+(5*8)+(4*2)+(3*9)+(2*7)+(1*9)=170
170 % 10 = 0
So 146829-79-0 is a valid CAS Registry Number.

A useful synthesis of ω-iodoperfluoroalkanesulfonyl fluorides and perfluoroalkane-α,ω-bis-sulfonyl fluorides
Qiu, Weiming,Burton, Donald J.
, p. 93 - 100 (1993)
ω-Iodoperfluoroalkanesulfonyl fluorides and perfluoroalkane-α,ω-bis-sulfonyl fluorides have been prepared via deiodosulfination, chlorination, and then chlorine-fluorine exchange reaction of α,ω-diiodoperfluoroalkanes I(CF2)nI (n=3, 4, 6).Similar reaction of I(CF2)2O(CF2)2SO2F affords FSO2(CF2)2O(CF2)2SO2F.
