3-Ethylpenta-1,3-dien is an organic compound with the molecular formula C7H12. It is a colorless liquid with a strong, pungent odor. This conjugated diene is characterized by a carbon chain of five carbons with a double bond between the first and third carbons, and a methyl group attached to the third carbon. Additionally, it has an ethyl group attached to the second carbon, which distinguishes it from other penta-1,3-dienes. 3-Ethylpenta-1,3-dien is used as a chemical intermediate in the synthesis of various organic compounds, particularly in the production of fragrances and pharmaceuticals. It is also known for its reactivity in Diels-Alder reactions, a type of chemical reaction that involves the formation of a six-membered ring from a conjugated diene and a dienophile.

687-79-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 687-79-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 687-79:
(5*6)+(4*8)+(3*7)+(2*7)+(1*9)=106
106 % 10 = 6
So 687-79-6 is a valid CAS Registry Number.

Pyrolysis of 3-Ethylpent-2-ene - a Further Evidence for a Homoallylic-Rearrangement

Bach, G.,Zychlinski, W.,Kopinke, F.-D.,Zimmermann, G.

, p. 677 - 682 (2007/10/02)

The pyrolysis of 3-ethylpent-2-ene has been studied under conditions of steam cracking in the temperature range 600-700 deg C in a laboratory scale tubular reactor.The main products of decomposition were methane, 2-ethylbutadiene and isoprene.The majority of products obviously arose from H abstraction and radical addition, typical for radical chain reactions in olefins decomposition including phenomena resulting from allylic resonance.The formation of isoprene, however, could only be explained by a reaction network including a homoallylic rearrangement.
