Bromocyclopentane-d9 is a deuterium-labeled derivative of bromocyclopentane, a halogenated cyclopentane compound. The d9 in its name signifies that all nine hydrogen atoms in the molecule have been substituted with deuterium atoms. This unique characteristic makes Bromocyclopentane-d9 a valuable reference standard and internal standard for mass spectrometry and nuclear magnetic resonance (NMR) studies. Its enhanced stability and clarity in spectroscopic analysis make it a crucial tool in chemical and pharmaceutical research.

Check Digit Verification of cas no

The CAS Registry Mumber 35468-44-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,4,6 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 35468-44:
(7*3)+(6*5)+(5*4)+(4*6)+(3*8)+(2*4)+(1*4)=131
131 % 10 = 1
So 35468-44-1 is a valid CAS Registry Number.

The relative rates of bromination of cyclohexane and cyclopentane with molecular bromine. Comparison of the reactions in solution and in vapor phase

Tanner, Dennis D.,Ruo, Tomoki C-S.,Takiguchi, Hideki,Guillaume, Andre

, p. 1368 - 1374 (2007/10/02)

The realtive rates of transfer of the cyclopentadienyl radical with molecular bromine and hydrogen bromide (k2'/k-1') and with hydrogen tribromide and hydrogen bromide (k3'/k-1') have been determined.The relative transfer rates are compared with the analogous values previously reported for the reactions of cyclohexyl radicals (k2/k-1 and k3/k-1).Utilizing the values of k2'/k-1' and k2/k-1 the competitive vapor phase rates of bromine atom abstraction of hydrogen from the two substrates could be obtained.An expression using a combination of the five sets of relative rate constants was used to determine the effect of competitive cage reversal which occurs in the solution phase bromination of the two substrate radicals with caged hydrogen bromide.For two structurally similar radicals, cage reversal (internal return) was found to affect the relative rates of bromination by 30 percent, while the relative transfer rates, although differing each by a factor of two, fortuitously nearly cancel each other's effect.The effect of both internal and external reversal reactions on the relative rates of bromination of structurally dissimilar substrates, halogenated alkanes and their parent hydrocarbons, is discussed.
