1453-38-9 Usage
General Description
1,1,2,3,4,5-HEXAFLUORO-2,3,4,5-TETRACHLOROCYCLOPENTANE is a chemical compound with the molecular formula C5Cl4F6. It is a highly fluorinated and chlorinated cyclopentane derivative. 1,1,2,3,4,5-HEXAFLUORO-2,3,4,5-TETRACHLOROCYCLOPENTANE is primarily used as an intermediate in the production of high-performance polymers, such as Teflon and other fluorinated materials. It is also used as a solvent and as a fire suppressant due to its non-flammable nature and high stability. Additionally, it is used in electronics and semiconductor industries as a cleaning agent. However, 1,1,2,3,4,5-HEXAFLUORO-2,3,4,5-TETRACHLOROCYCLOPENTANE is known to be environmentally persistent and potentially toxic, and its use is regulated in many countries due to its potential adverse effects on human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 1453-38-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,5 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1453-38:
(6*1)+(5*4)+(4*5)+(3*3)+(2*3)+(1*8)=69
69 % 10 = 9
So 1453-38-9 is a valid CAS Registry Number.

Reactions of 1,2,3,4,5-Pentafluorocyclopentadiene
Paprott, Gerhard,Lehmann, Sabine,Seppelt, Konrad
, p. 727 - 734 (2007/10/02)
The synthesis of 1,2,3,4,5-pentafluorocyclopentadiene (2) from 1,2,3,4,5-pentachloro-1,2,3,4,5-pentafluorocyclopentane (1) is closely investigated.Side-products are 1,2,3,4-tetrafluorocyclopentadiene (4) and 5-chloro-1,2,3,4-tetrafluorocyclopentadiene (5).Under UV irradiation, 2 isomerizes to give 1,2,3,5,5-pentafluorocyclopentadiene (6). 2 dimerizes forming a mixture of Diels-Alder products.This dimerisation is irreversible until 700 deg C.The hydrogen in 2 can be replaced by bromine forming 7. 2 adds Cl2, Br2, I2, and carbonylmetal hydrides.Also with the most stable salt Tl(+)C5F5(-) (8) the synthesis of a η5-C5F5 complex was unsuccessful.A modified synthesis of hexafluorocyclopentadiene (12) from hexachlorocyclopentadiene (9) is presented. 12 adds AsF5 forming c-C5F7AsF4 (13).With SbF5 no cation c-C5F5(+) (14) could be detected so far.
