431-78-7 Usage
Uses
Used in Firefighting Applications:
2,3-DIBROMO-1,1,1,3,3-PENTAFLUOROPROPANE is used as a fire extinguishing agent for its effectiveness in combating fires, particularly in situations where water or other extinguishing agents are not suitable.
Used in Pharmaceutical and Organic Chemical Manufacturing:
In the pharmaceutical and organic chemical industries, 2,3-DIBROMO-1,1,1,3,3-PENTAFLUOROPROPANE is used as a key intermediate in the synthesis of various compounds due to its unique chemical properties.
Environmental Considerations:
Despite its applications, 2,3-DIBROMO-1,1,1,3,3-PENTAFLUOROPROPANE is recognized for its harmful effects on the ozone layer. As a result, its production and use have been restricted under the Montreal Protocol on Substances that Deplete the Ozone Layer to mitigate its environmental impact.
Transition to Alternatives:
Given the environmental concerns associated with 2,3-DIBROMO-1,1,1,3,3-PENTAFLUOROPROPANE, there is a global shift towards adopting more environmentally friendly alternatives for fire extinguishing and other applications, ensuring the protection of the ozone layer and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 431-78-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 431-78:
(5*4)+(4*3)+(3*1)+(2*7)+(1*8)=57
57 % 10 = 7
So 431-78-7 is a valid CAS Registry Number.

A facile route to tetrafluoroallene
Lu, Hengyao,Friedrich, H. Bruce,Burton, Donald J.
, p. 83 - 86 (2007/10/03)
Tetrafluoroallene has been prepared in 72percent-75percent yield by metallation of either 2-hydropentafluoropropene or 2-bromopentafluoropropene with t-butyllithium followed by thermal elimination of lithium fluoride from the 2-lithiopentafluoropropene.The 2-bromopentafluoropropene route gives the allene free of isobutane. - Keywords: Allenes; Lithium reagents; Metallation reactions; Elimination reactions; IR spectroscopy
