755-21-5 Usage
Uses
Used in Refrigeration and Air Conditioning Systems:
1,1,2,2,3,3,4,4-Octafluoro-5-chloropentane is utilized as a refrigerant in various refrigeration and air conditioning systems due to its environmentally friendly properties. Its low global warming potential and ozone depletion potential make it a preferred choice over other refrigerants that may contribute to environmental degradation.
Used in Foam Insulation Production:
In the manufacturing of foam insulation, 1,1,2,2,3,3,4,4-Octafluoro-5-chloropentane serves as a blowing agent. This role is crucial for the production of effective insulation materials that provide thermal efficiency and energy conservation in buildings. Its use in this application contributes to the creation of energy-efficient and sustainable construction materials.
Check Digit Verification of cas no
The CAS Registry Mumber 755-21-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,5 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 755-21:
(5*7)+(4*5)+(3*5)+(2*2)+(1*1)=75
75 % 10 = 5
So 755-21-5 is a valid CAS Registry Number.

A synthesis has been developed for α,α,ω-trihydrohaloperfluoroalkanes, H(CF2CF2)n*CH2X, where X is Cl or Br and n is 1 or 4.It is based on the cleavage of the aromatic sulfonate esters of α,α,ω-trihydroperfluoroalkan-α-ols by alkali metal halides.
α,α-DISUBSTITUTED POLYFLUOROALKANES

The reaction of 1,1,ω-trihydropolyfluoro-1-alkanols with triphenyldichloro- and triphenyldibromophosphorus gave 1-chloro- and 1-bromo-1,1,ω-trihydropolyfluoroalkanes.The 1,2-elimination of HF from the alkanes by the action of basic agents led to the formation of 1-chloro(bromo)-1,ω-dihydropolyfluoro-1-alkenes in the E form. 1,2-Dehalogenation (1-Br, 2-F) of the 1-bromo-1,1,ω-trihydropolyfluoroalkanes by the action of zinc made it possible to obtain the 1,1,ω-trihydropolyfluoro-1-alkenes. 1,2-Dehalogenation (1-Cl, 2-F) of the 1-chloro-1,1,ω-trihydropolyfluoroalkanes does not take place under analogous conditions.
