Perfluoropentane-1-sulphonyl fluoride, also known as PFOSF, is a synthetic chemical compound with the molecular formula C5F12SO2F. It is a colorless, odorless, and non-flammable liquid that is highly resistant to degradation due to its stable carbon-fluorine bonds. PFOSF is primarily used as an intermediate in the production of various perfluorinated compounds, such as perfluorinated surfactants and perfluoropolyethers, which have applications in industries like electronics, aviation, and textiles. However, due to its persistence in the environment and potential health risks, its production and use have been restricted under international agreements like the Stockholm Convention on Persistent Organic Pollutants.

375-81-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 375-81-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,7 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 375-81:
(5*3)+(4*7)+(3*5)+(2*8)+(1*1)=75
75 % 10 = 5
So 375-81-5 is a valid CAS Registry Number.

Die elektrochemische fluorierung von alkansulfonamiden und alkandisulfonamiden

Satori,Juenger

, p. 71 - 75 (2007/10/03)

Alkane sulphonylamides and disulphonylamides are stable in anhydrous (HF)x and undergo quantitative fission of S-N bonds during electrochemical fluorination. Besides NF3, the corresponding perfluoroalkane sulphonyl fluorides and disulphonyl fluorides are formed.
