Nantucket pine tip moth, Rhyacionia frustrana: identification of two sex pheromone components was written by Hill, Ada S.;Berisford, C. Wayne;Brady, U. Eugene;Roelofs, Wendell L.. And the article was included in Journal of Chemical Ecology in 1981.Quality Control of (E)-Dodeca-9,11-dien-1-yl acetate The following contents are mentioned in the article:
Two compounds identified as components of the sex pheromone system of R. frustrana are (E)-9-dodecen-1-yl acetate (I) [35148-19-7] and (E)-9,11-dodecadien-1-yl acetate (II) [50767-78-7], which were found in female gland extracts in the ratio of 96:4, resp. The identifications were based on chem. and instrumental anal., electroantennogram studies, and field trapping tests. The optimum ratio for trapping male R. frustrana was from 95:5 to 97.5:2.5 (I:II), when dispensed from rubber septa at a loading of â?000 μg/lure. In addition to these 2 compounds, evidence was obtained for the presence of dodecan-1-ol [112-53-8] and (E)-9-dodecen-1-ol [35237-62-8] in female tip extracts and in female effluvium, and for dodecan-1-yl acetate [112-66-3] in female tip extracts This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Quality Control of (E)-Dodeca-9,11-dien-1-yl acetate).
(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. 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.Quality Control of (E)-Dodeca-9,11-dien-1-yl acetate
