(1-~3~H)cyclopentene is a hydrogen-labeled derivative of cyclopentene, a cyclic hydrocarbon with the molecular formula C5H8. In (1-~3~H)cyclopentene, two of the hydrogen atoms are replaced with tritium, a radioactive isotope of hydrogen, resulting in the molecular formula C5H6T2. This labeled compound is primarily used in chemical research and as a tracer in various applications, such as studying reaction mechanisms and metabolic pathways. The presence of tritium allows for the detection and tracking of the molecule through radioactive decay, providing valuable insights into chemical processes.

Check Digit Verification of cas no

The CAS Registry Mumber 37729-44-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,7,2 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 37729-44:
(7*3)+(6*7)+(5*7)+(4*2)+(3*9)+(2*4)+(1*4)=145
145 % 10 = 5
So 37729-44-5 is a valid CAS Registry Number.

Catalytic Reactions of Cyclopentene over Zinc Oxide

Brown, Ronald,Kemball, Charles,Taylor, Duncan

, p. 2329 - 2350 (2007/10/02)

Reactions of cyclopentene with hydrogen or deuterium have been followed on zinc oxide in the temperature range from 324 to 371 K using gas chromatography or mass spectrometry and samples of the products have been examined by deuterium n.m.r. spectroscopy.With deuterium an exchange reaction occurs leading to the stepwise replacement of the two olefinic hydrogen atoms by a mechanism involving the formation of cyclopentenyl intermediates.Cyclopentane is also produced but a rate which is slower than the exchange of cyclopentene.The process is controlled by the rate of formation of cyclopentyl radicals which do not readily dissociate again to alkene.Deuterium n.m.r. spectroscopy has potential for identifying and estimating groupings of deuterium atoms in cyclopentane.
