Uses
Different sources of media describe the Uses of 376-90-9 differently. You can refer to the following data:
1. 2,2,3,3,4,4-Hexafluoro-1,5-pentanediol can be used for the preparation of cyclic and acyclic polyfluorosiloxanes as precursors to per- and polyfluoroethers.
2. Used for the preparation of cyclic and acyclic polyfluorosiloxanes as precursors to per- and polyfluoroethers.
Check Digit Verification of cas no
The CAS Registry Mumber 376-90-9 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 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 376-90:
(5*3)+(4*7)+(3*6)+(2*9)+(1*0)=79
79 % 10 = 9
So 376-90-9 is a valid CAS Registry Number.

Process for hydroxyalkylation of fluorinated alcohols
-
, (2008/06/13)
Mono O-hydroxyalkylated derivatives of 1,1-dihydroperfluorinated or 1H,1-alkylperfluorinated alcohols are prepared by reacting the alcohols with alkylene carbonates at a temperature of at least 60° C. in the presence of a one- or two-part catalyst. The catalyst is a nitrogenous base, optionally in combination with a tetraalkylammonium halide. The O-hydroxyalkylated derivatives are useful non-ionic surfactants and emulsifiable compounds for fire extinguishing systems.
