Mass spectra of dodecadienic compounds with a conjugated double bond, lepidopterous sex pheromones was written by Ando, Tetsu;Katagiri, Yoshio;Uchiyama, Masaaki. And the article was included in Agricultural and Biological Chemistry in 1985.Recommanded Product: (E)-Dodeca-9,11-dien-1-yl acetate The following contents are mentioned in the article:
All geometrical isomers of 5,7-, 6,8-, 7,9-, 8,10- and 9,11-dodecadien-1-ols, and their acetates and aldehyde derivatives were analyzed by electron impact mass spectrometry. The abundance of mol. ion (M+) was observed in every spectrum, and the relative intensity of M+ tended to be strong if the compound possessed an (E)-double bond(s). In addition to M+, [M – H2O]+ (alcs.) and [M – CH3CO2H]+ (acetates), every dienic compound showed typical series of CnH2n-2+ â?CnH2n-5+ with abundance maximum around C4, C5, C6 or C7. Each double bond positional isomer characteristically yielded different ion peaks in the series, which were useful for its distinction from other isomers. These results indicate that the chem. structure of a natural pheromone of Lepidoptera is easily deduced successfully by GC-MS anal. if it is a conjugated dienic pheromone. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Recommanded Product: (E)-Dodeca-9,11-dien-1-yl acetate).
(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: (E)-Dodeca-9,11-dien-1-yl acetate
