General Description
Colorless odorless liquid. Nonflammable.
Air & Water Reactions
Slightly soluble in water.
Reactivity Profile
1,2-dichloro-1,1,2,3,3-pentafluoro-propane is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. They suffer oxidation with strong oxidizing agents and under extremes of temperature.
Check Digit Verification of cas no
The CAS Registry Mumber 422-44-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 422-44:
(5*4)+(4*2)+(3*2)+(2*4)+(1*4)=46
46 % 10 = 6
So 422-44-6 is a valid CAS Registry Number.

Selective reduction of halopolyfluorocarbons by organosilicon hydrides
Petrov, Viacheslav A.
, p. 7294 - 7297 (2007/10/03)
It is demonstrated that silicon hydrides can be used for reduction of polyfluorinated halocarbons. For example, the reaction between CF3CCl2F and excess triethylsilane, catalyzed by benzoyl peroxide, leads to the formation of a mixture containing CF3CHClF (major), CF3CH2F, and ClSi(C2H5)3. On the other hand, the reaction of chlorofluoroalkanes, containing an internal -CCl2- group readily proceeds with reduction of both chlorines, leading to compounds such as (CF3)2CH2 and CF3CH2C2F5. In contrast to chlorofluoroalkanes, bromofluoroalkanes are much more reactive and reaction with hydrosilane rapidly proceeds without the catalyst at elevated temperature.
