1428-33-7 Usage
General Description
ALLYL 1,1,2,2-TETRAFLUOROETHYL ETHER, also known as allyl perfluorovinyl ether, is a chemical compound with the molecular formula C5H4F8O. It is a colorless, flammable liquid with a faint sweet odor. ALLYL 1,1,2,2-TETRAFLUOROETHYL ETHER is primarily used as a monomer in the production of perfluorocarbon polymers, which have applications in making films, coating, and other industrial products. It is also used as a reactive intermediate in the synthesis of other chemicals and materials. Allyl 1,1,2,2-tetrafluoroethyl ether is known to be highly stable and inert, with low reactivity towards most common chemical reactions. However, it should be handled carefully due to its flammability and potential for hazardous reactions with certain chemicals.
Check Digit Verification of cas no
The CAS Registry Mumber 1428-33-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,2 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1428-33:
(6*1)+(5*4)+(4*2)+(3*8)+(2*3)+(1*3)=67
67 % 10 = 7
So 1428-33-7 is a valid CAS Registry Number.

Cyclizations of 5-hexenyl, 6-heptenyl, 7-octenyl, and 8-nonenyl radicals. The kinetic and regiochemical impact of fluorine and oxygen substituents

Using competition kinetic methodology, rate constants for cyclizations of a series of hydrofluorocarbon (HFC) and ether 5-hexenyl, 6-heptenyl, and 7-octenyl radicals have been determined. Remarkably large rate constants (> 107 s-1) have been observed for 6-exo-cyclizations of 1,1,2,2-tetrafluoro- and 1,1,2,2,3,3,4,4,-octafluoro-6-heptenyl radicals (> 103 those of analogous hydrocarbon radicals), whereas HFC hexenyl and heptenyl ethers exhibit lower cyclization reactivity, as do HFC 7-octenyl radical systems, which cyclize in an endo manner. HFC 8-nonenyl radicals were not observed to cyclize. The results can be rationalized in terms of transition state polar influences, though other factors may also play significant roles.
