16824-14-9 Usage
General Description
3-Methylbuta-1,3-dien-2-yl acetate, commonly known as isoprenyl acetate, is an organic compound that typically appears as a colorless liquid. As a derivative of isoprene, it possesses a?fruity odor and is often used as a flavoring agent in the food industry. Its structure consists of a five-carbon backbone with an acetate group attached to the second carbon and a double bond on the first and third carbons. It showcases relative stability, although it can polymerize upon exposure to light or heat. Its synonyms include Isopenten-2-yl acetate, 3-Methyl-1,3-butadien-2-yl acetate.
Check Digit Verification of cas no
The CAS Registry Mumber 16824-14-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,2 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16824-14:
(7*1)+(6*6)+(5*8)+(4*2)+(3*4)+(2*1)+(1*4)=109
109 % 10 = 9
So 16824-14-9 is a valid CAS Registry Number.

Ruthenium-Catalyzed Selective Addition of Carboxylic Acids to Alkynes.A Novel Synthesis of Enol Esters
Mitsudo, Take-aki,Hori, Yoji,Yamakawa, Yasushi,Watanabe, Yoshihisa
, p. 2230 - 2239 (2007/10/02)
Carboxylic acids react with alkynes in the presence of a catalytic amount of bis(ν5-cyclooctadienyl)ruthenium/trialkylphosphine/maleic anhydride in toluene at 60-80 deg.C to give enol esters having a terminal methylene group in good to excellent yields with high regioselectivity.The deuterium distributions in the products of the reaction of acetic acid-d with 1-hexyne and ethyl propargyl carbonate were examined.Kinetic measurments revealed that the rate has first-order dependence on carboxylic acid, alkyne, and the initial concentration of the ruthenium catalyst.
