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 C_nH_2n-2⁺ âˆ?C_nH_2n-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

Alkylation of I (R = Bu, heptyl, R³, R¹ = H) gave 55-71% trans–I (R¹ = Bu, heptyl, Me) together with 1-9% of the corresponding cis–I. Thermolysis of trans–I in octane gave (E,Z)-R¹CH:CHCH:CHR, whereas in EtOH in the presence of base (E,E)-R¹CH:CHCH:CHR were obtained quant. Ether cleavage of I (R = R², R¹ = H; R = R³, R¹ = Me), followed by thermolysis, gave (E)-CH₂:CHCH:CH(CH₂)₈OAc and (E,E)-MeCH:CHCH:CH(CH₂)₇OH resp.

The chem. compositions of the volatile oil had been separated and identified by means of Gas Chromatog.-Mass Spectrometry. Twenty nine compositions were identified from 36 separated peaks, and the major components were oxacyclotetradecan-2-one, 13-methyl- (23.53%), 9,12-octadecadienoic acid (Z,Z)- (17.56%), selinene (12.37%), hexadecanoic acid (8.20%), 9-hexadecenoic acid (7.84%), (-)-lepidozenal (7.82%), etc., which were made up to 97.76% of the quantity of volatile oil. The antimicrobial activity of the volatile oil was preliminarily tested in the suspensions of Escherichia coli, Staphylococcus aureus, Saccharomyces cerevisiae, Candida albicans, Aspergillus niger, Penicillium chrysogenum and Rhizopus nigricans, resp., when the volatile oil was diluted by 100 times, 50 times and 25 times. The results showed that P. chrysogenum and S. cerevisiae were the most sensitive, next R. nigricans and A. niger, and then C. albicans, S. aureus and E. coli.

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. Polyesters are important plastics, with monomers linked by ester moieties. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: (E)-Dodeca-9,11-dien-1-yl acetate
