42532-60-5 Usage
General Description
Perfluoroisobutyronitrile (PFIBN) is a chemical compound that is part of the perfluorinated compounds (PFCs) group. Its high electron affinity makes it an effective and efficient etchant for microelectronic devices. Its full chemical formula is C4F7N, and it is known for being colorless and having a pungent smell. Moreover, it is mostly used in the production of semiconductors and electronics due to its etching properties. PFIBN is not typically found in the environment due to its non-natural origins, but if mishandled or improperly disposed of, it can be hazardous to both the environment and human health.
Check Digit Verification of cas no
The CAS Registry Mumber 42532-60-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,3 and 2 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 42532-60:
(7*4)+(6*2)+(5*5)+(4*3)+(3*2)+(2*6)+(1*0)=95
95 % 10 = 5
So 42532-60-5 is a valid CAS Registry Number.

Reaction of i-Heptafluoropropyl Radicals with Cyanogen Chloride
Voehringer, Cecilia M. de,Staricco, Eduardo H.
, p. 2631 - 2638 (2007/10/02)
The gas-phase reaction of i-C3F7 radicals with cyanogen chloride has been studied between 70 and 330 deg C, using heptafluoro-2-iodopropane as the free-radical source.The main product, 2-chloroheptafluoropropane, is formed via chlorine-atom abstraction by i-C3F7: i-C3F7 + ClCN -> C3F7Cl + CN (6) for which log106/k1/2/c)/cm3/2mol-1/2s-1/2> = 6.27-14.41/2.303 RT was obtained.At lower temperatures the Arrhenius plot shows curvature.This was interpreted as the occurence of another reaction producing C3F7Cl, wich could be i-C3F7 + ClCN C3F7ClCN (9.-9) C3F7ClCN -> C3F7Cl + CN (10).The results are compared with those for the reaction of other perfluoroalkyl radicals with ClCN.
