5-Ethylidenecyclopenta-1,3-diene is a conjugated diene with a molecular formula of C7H8. It is a cyclic hydrocarbon compound consisting of five carbon atoms in a cyclopentane ring structure, with an ethylidene group (CH2=CH-) attached to the fifth carbon atom. 5-ethylidenecyclopenta-1,3-diene is known for its aromatic properties due to the extended conjugation of the double bonds, which allows for delocalization of electrons across the molecule. It is an important intermediate in organic synthesis and can be used in the preparation of various pharmaceuticals, polymers, and other chemical products. The compound is also notable for its reactivity, particularly in Diels-Alder reactions, where it can act as a diene to form new carbon-carbon bonds with dienophiles.

3839-50-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3839-50-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,3 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3839-50:
(6*3)+(5*8)+(4*3)+(3*9)+(2*5)+(1*0)=107
107 % 10 = 7
So 3839-50-7 is a valid CAS Registry Number.

Srinivasan, Ra.,Baum, Thomas,Epling, Gary

, p. 437 - 438 (2007/10/02)

Irradiation of quadricyclene in solution leads to isomeric products in addition to bicyclohepta-2,5-diene, which reduces its usefulness in solar energy storage.
