3-Ethyl-1,2-pentadiene is an organic compound with the molecular formula C7H12. It is a colorless liquid with a strong, pungent odor. This conjugated diene features a carbon-carbon double bond at the 1 and 2 positions, and an additional double bond at the 3 and 4 positions, with an ethyl group (CH2CH3) attached to the 3rd carbon. 3-Ethyl-1,2-pentadiene is an important intermediate in the synthesis of various chemicals, such as polymers and pharmaceuticals, due to its reactive diene system. It is also used as a solvent and a chemical building block in the production of fragrances and flavorings. The compound is sensitive to air and light, and should be stored under an inert atmosphere to prevent polymerization or other unwanted reactions.
The CAS Registry Mumber 2384-96-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,8 and 4 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2384-96: (6*2)+(5*3)+(4*8)+(3*4)+(2*9)+(1*6)=95 95 % 10 = 5 So 2384-96-5 is a valid CAS Registry Number.
