375-26-8 Usage
Uses
Used in Fire Suppression Systems:
2,3-DIBROMOOCTAFLUOROBUTANE is used as a fire extinguishing agent for its effectiveness in suppressing fires. Its high boiling point and low vapor pressure contribute to its performance in fire suppression applications.
Used as a Brominated Flame Retardant:
In the industry, 2,3-DIBROMOOCTAFLUOROBUTANE is utilized as a brominated flame retardant to enhance the fire resistance of various materials, thereby improving their safety characteristics.
Environmental and Health Concerns:
Despite its utility, 2,3-DIBROMOOCTAFLUOROBUTANE is recognized as potentially harmful to the environment and human health due to its persistence in the atmosphere and contribution to ozone depletion. As a result, there is an ongoing search for alternative fire extinguishing agents that are both safer and more environmentally friendly to mitigate these risks.
Check Digit Verification of cas no
The CAS Registry Mumber 375-26-8 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, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 375-26:
(5*3)+(4*7)+(3*5)+(2*2)+(1*6)=68
68 % 10 = 8
So 375-26-8 is a valid CAS Registry Number.

Preparation of the E- and Z-heptafluorobutenyl-2-zinc reagent by zinc-induced dehalogenation/metallation of 2,2-dibromo-octafluorobutane
Morken, Peter A.,Campbell, Robert F.,Burton, Donald J.
, p. 81 - 86 (2007/10/02)
The AlCl3-catalyzed isomerization of CF3CFBrCFBrCF3 afforded CF3CF2CBr2CF3, which upon treatment with 2 equiv. zinc in DMF underwent dehalogenation/metallation to afford a 1:1 mixture of E- and Z-CF3CF=C(ZnX)CF3 in 96percent 19F NMR yield.The zinc reagent exhibited poor thermal stability in DMF and completely decomposed by a β-elimination route in 24 h at 60 deg C.However, the zinc reagent prepared from E- and Z-CF3CF=CICF3 in triglyme showed enhanced thermal stability and gave E- and Z-p-NO2C6H4C(CF3)=CFCF3 in a palladium-catalyzed coupling reaction with p-NO2C6H4I.
