1-Bromo-1-chloro-1,2,2,2-tetrafluoroethane, also known as C2H2BrClF4, is a halogenated hydrocarbon with the molecular formula C2H2BrClF4. It is a colorless, volatile liquid with a pungent odor. Ethane, 1-bromo-1-chloro-1,2,2,2-tetrafluoro- is a derivative of ethane, where one hydrogen atom is replaced by a bromine atom, another by a chlorine atom, and two hydrogen atoms are replaced by fluorine atoms. Due to its unique structure, it exhibits properties such as high chemical stability, low reactivity, and low boiling point. It has potential applications in various fields, including refrigerants, solvents, and fire extinguishing agents. However, it is essential to handle Ethane, 1-bromo-1-chloro-1,2,2,2-tetrafluoro- with care, as it can be harmful to human health and the environment due to its potential to contribute to ozone depletion and global warming.

Check Digit Verification of cas no

The CAS Registry Mumber 754-20-1 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 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 754-20:
(5*7)+(4*5)+(3*4)+(2*2)+(1*0)=71
71 % 10 = 1
So 754-20-1 is a valid CAS Registry Number.

Synthesis of functionalized polyfluoroalkyl hypochlorites and fluoroxy compounds and their reactions with some fluoroalkenes

Randolph, Bruce B.,DesMarteau, Darryl D.

, p. 129 - 150 (2007/10/02)

Several new polyfluoroalkyl hypochlorites and fluoroxy compounds containing Cl, H and Br in the alkyl group have been prepared and characterized by 19F NMR, 1H NMR and IR spectroscopies and by their reactions with fluoroalkenes to produce new polyfluoroethers.The novel compounds are prepared by the CsF-catalyzed addition of F2 or ClF to the C=O bond in CF3C(O)CF2Cl, ClCF2C(O)CF2Cl, and their derivatives HCF2C(O)CF3 and HCF2C(O)CF2Cl.Compounds containing an α-CF3 group exhibit enhanced thermal stability.New fluoroxy compounds and hypochlorites have also been prepared from the acid fluorides CF3-CFX-C(O)F (X = Cl, Br), which are obtained by the ring-opening reaction of hexafluoropropene oxide with (CH3)3SiCl, LiBr and (C2H5)3SiBr.These -OX compounds behave similarly to previously known materials with two α-F atoms, decomposing quickly at room temperature to COF2 and haloalkanes.
