9,11-Dodecadienyl alcohols, acetates, or aldehydes as synthetic chemical sex attractants for four lepidoptera: Cosmopterix gemmiferella (Clemens), Dichrorampha simulana (Clemens), Tortricidia testacea (Packard), and an Ancylis sp. was written by Chisholm, M. D.;Reed, D. W.. And the article was included in Journal of Chemical Ecology in 1985.Formula: C14H24O2 The following contents are mentioned in the article:

Four Lepidoptera were lured to field traps containing various combinations of 9,11-dodecadienes with alc., acetate, or aldehyde functional groups. All species required 2 chem. components for best attraction. C. gemmiferella Was most responsive to a combination of (9Z)-9,11-dodecadienyl acetate and (9E)-9,11-dodecadienyl acetate in a 2:1 ratio; (D. simulana to (9E)-9,11-dodecadienyl acetate and (9E)-9,11-dodecadien-1-ol in a 10:1 ratio; T. testacea to (9Z)-9,11-dodecadienal and (9E)-9,11-dodecadienal in a 10:1 ratio; and Ancylis to (9Z)-9,11-dodecadienyl acetate and (9Z)-9,11-dodecadien-1-ol a 10:1 ratio. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Formula: C14H24O2).

(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. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Formula: C14H24O2

Superhydrophobic behavior of coatings based on fluoroalkyl methacrylate copolymers on a textured aluminum surface was written by Klimov, V. V.;Bryuzgin, E. V.;Navrotskiy, A. V.;Novakov, I. A.. And the article was included in Surfaces and Interfaces in 2021.Electric Literature of C7H6F6O2 The following contents are mentioned in the article:

This study involved the modification of a textured aluminum surface with reactive fluoroalkyl methacrylate copolymers with short-chain fluoroalkyl radicals and glycidyl methacrylate to achieve superhydrophobic properties. The resulting grafted polymer coatings are characterized by contact angles up to 170° and roll-off angles of 2-3°. The multimodal texture of the modified aluminum surface layer, namely, the etching depth and the penetration depth of polymeric modifiers, has been investigated by SEM and energy dispersive X-ray spectroscopy. This study demonstrates an increase in the stability of the heterogeneous wetting regime of superhydrophobic coatings based on fluoroalkyl methacrylate copolymers due to multiple attachment of the polymeric modifier to the surface. This study involved multiple reactions and reactants, such as 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3Electric Literature of C7H6F6O2).

1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3) 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. 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.Electric Literature of C7H6F6O2

(2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5) 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. 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.Related Products of 37905-02-5

On the photolysis of phthalic acid dialkyl esters: a product analysis study was written by Hizal, G.;Zhu, Q. Q.;Fischer, Ch.-H.;Fritz, P. M.;Schnabel, W.. And the article was included in Journal of Photochemistry and Photobiology in 1993.HPLC of Formula: 5444-75-7 The following contents are mentioned in the article:

The following phthalate esters were subjected to UV irradiation (λ_inc = 254 nm at 22° or λ_inc = 240-440 nm at 40°): bis(2-ethylhexyl) (DOP), dioctyl (DNOP), didecyl (DDP), and di-Me (DMP). In all cases (except DMP) analogous major photoproducts, identified by the gas chromatog.-mass spectrometry method, are formed: 1-alkenes, alkyl alcs., phthalic anhydride, 2-formylbenzoic acid esters and benzoic acid esters. Generally, the quantum yields of decomposition are quite low: φ ≤0.03. Extension of the linear alc. chains decreases the stability: φ(DMP) < φ(DNOP) < φ(DDP). In the absence of O₂, DOP, which contains branches in the alc. chains, is more stable than the isomeric DNOP containing linear alc. chains: φ(-DOP) < φ(-DNOP). This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7HPLC of Formula: 5444-75-7).

2-Ethylhexyl benzoate (cas: 5444-75-7) 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. 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.HPLC of Formula: 5444-75-7

Ortho selectivity in S_NAr substitutions of 2,4-dihaloaromatic compounds. Reactions with piperidine was written by Wendt, Michael D.;Kunzer, Aaron R.. And the article was included in Tetrahedron Letters in 2010.Quality Control of tert-Butyl 2,4-difluorobenzoate The following contents are mentioned in the article:

A broad survey of aromatic compounds with halogens positioned both ortho and para to activating groups was studied in S_NAr reactions with piperidine. Regioselectivities varied with the substituent group and the polarity of the solvent. Many activating groups exhibited an overall bias toward ortho-substitution, and this led in nonpolar solvents to very high ortho selectivity. More polar solvents uniformly shifted the product ratio toward para substitution. Evidence is presented that argues for coordination via hydrogen bonding as a driver of much of the ortho selectivity observed The data presented show ample evidence of the generality and synthetic utility of the ortho-directing ability of several common activating groups for this reaction type. This study involved multiple reactions and reactants, such as tert-Butyl 2,4-difluorobenzoate (cas: 500353-15-1Quality Control of tert-Butyl 2,4-difluorobenzoate).

tert-Butyl 2,4-difluorobenzoate (cas: 500353-15-1) 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 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.

Enantiospecific synthesis of a novel rearranged eunicellane diterpenoid by SmI₂-mediated cyclization was written by Schoettner, Elisabeth;Jones, Peter G.;Lindel, Thomas. And the article was included in Synthesis in 2009.Reference of 37905-02-5 The following contents are mentioned in the article:

Aiming at the assembly of marine-derived diterpenoids, the synthesis and cyclization of α-geranylated carvones was investigated. 3-Hydroxyalkylation of side-chain hydrogenated carvone with geraniol-derived aldehydes gave access to diterpenoid allyl phosphates, e.g. I. It was shown that retro-aldol fragmentation of ring-hydrogenated 3-(hydroxyalkyl)carvones is surprisingly facile, because the preferred conformation resembles a Zimmerman-Traxler type transition-state. The hitherto unknown rearranged eunicellane skeleton II can be obtained in one step by treatment of the α,β-unsaturated diterpenoid I with samarium diiodide generated in situ in THF. NOESY-based structure anal. revealed the presence of an ansa bridge across a twist-boat six-membered ring.

Synthesis and Activity of Fluorescent Isoprenoid Pyrophosphate Analogues was written by Kim, MeeKyoung;Kleckley, Troy S.;Wiemer, Andrew J.;Holstein, Sarah A.;Hohl, Raymond J.;Wiemer, David F.. And the article was included in Journal of Organic Chemistry in 2004.Application In Synthesis of (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate The following contents are mentioned in the article:

New fluorescent analogs of farnesol and geranylgeraniol were prepared and then converted to the corresponding pyrophosphates. These analogs incorporate anthranylate or dansyl-like groups anchored to the terpenoid skeleton through amine bonds that would be expected to be relatively stable to metabolism After addition of the alcs. or the pyrophosphates to the culture medium, their fluorescence is readily observed inside a human-derived leukemia cell line. Enzyme assays have revealed that the farnesyl pyrophosphate analog is an inhibitor of FTase, while the corresponding alc. is not. These results, together with Western blot analyses of cell lysates, indicate that the farnesyl pyrophosphate analog penetrates the cells as an intact pyrophosphate and that it does so at a biol. relevant concentration This study involved multiple reactions and reactants, such as (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5Application In Synthesis of (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate).

Hysteresis-free polymer-stabilized blue phase liquid crystals comprising low surface tension monomers was written by Hsieh, Pao-Ju;Chen, Huang-Ming Philip. And the article was included in Liquid Crystals in 2015.Recommanded Product: 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate The following contents are mentioned in the article:

Partial replacement of fluoroacrylates in the monomer composition is able to reduce the free energy of polymer-stabilized blue phase liquid crystal (PSBPLC) due to their low surface tension. The ease of blue phase platelet texture formation is observed under fast cooling and short annealing time before UV irradiation The peak driving voltages are dramatically decreased from 9% to 16% in the resulting PSBPLCs. In addition, the hysteresis is completely suppressed in the PSBPLC containing 3FM-M1. The other PSBPLC containing fluoroacrylates retain very small hysteresis (ΔV < 0.8 V) regardless the fluorine atom numbers In comparison with current PSBPLCs, the fluoroacrylates serve as mesophase enhancer not only to promote the blue phase formation but also to improve the electro-optical properties. This study involved multiple reactions and reactants, such as 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3Recommanded Product: 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate).

Zwitterionic sulfobetaine inhibitors of squalene synthase was written by Spencer, Thomas A.;Onofrey, Thomas J.;Cann, Reginald O.;Russel, Jonathon S.;Lee, Laura E.;Blanchard, Daniel E.;Castro, Alfredo;Gu, Peide;Jiang, Guojian;Shechter, Ishaiahu. And the article was included in Journal of Organic Chemistry in 1999.COA of Formula: C12H18O3 The following contents are mentioned in the article:

A number of sulfobetaines were synthesized and evaluated as inhibitors of squalene synthase (SS) on the basis of the idea that their zwitterionic structure would have properties conducive both to binding in the active site and to passage through cell membranes. When the simple sulfobetaine moiety is incorporated into compounds containing hydrophobic portions like those in farnesyl diphosphate or presqualene diphosphate, inhibition of SS in a rat liver microsomal assay was indeed observed A wide variety of structural modifications was investigated. Unfortunately, no inhibitors in the submicromolar range were discovered, and exploration of a different type of zwitterion seems necessary if this appealing approach to inhibition of SS is going to provide a potential antihypercholesterolemic agent. This study involved multiple reactions and reactants, such as (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5COA of Formula: C12H18O3).
