Isolation and identification of the female sex pheromones of the red bollworm moth, Diparopsis castanea was written by Nesbitt, Brenda F.;Cole, Beevor R. A.;Lester, R.;Poppi, R. G.. And the article was included in Journal of Insect Physiology in 1975.Application of 50767-78-7 The following contents are mentioned in the article:

The major female sex pheromone of D. castanea was 9,11-dodecadien-1-yl acetate (80:20 trans:cis). Minor components were trans-9-dodecen-1-yl acetate, 11-dodecen-1-yl acetate, and dodecan-1-yl acetate. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Application of 50767-78-7).

(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application of 50767-78-7

(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. 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.Related Products of 50767-78-7

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 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 contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Use of carbon-13 NMR spectroscopy for assigning the configuration of carbon-carbon double bonds of monoenic or dienic pheromone components and for quantitative determination of Z/E mixtures was written by Rossi, Renzo;Carpita, Adriano;Quirici, Maria G.;Veracini, Carlo Alberto. And the article was included in Tetrahedron in 1982.SDS of cas: 50767-78-7 The following contents are mentioned in the article:

The configuration of mono- and dienic insect pheromones was determined from chem.-shift differences of the allylic C atoms between unsaturated and the corresponding saturated pheromones. The method avoids use of the nuclear Overhauser effect and allows quant. determination of the stereoisomeric composition of mixtures of synthetic mono- and dienic pheromone components. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7SDS of cas: 50767-78-7).

(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. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.SDS of cas: 50767-78-7
