Hydrophilic surfaces via the self-assembly of nitrile-terminated alkanethiols on gold was written by Park, Chul Soon;Zenasni, Oussama;Marquez, Maria D.;Moore, H. Justin;Lee, T. Randall. And the article was included in AIMS Materials Science in 2018.Recommanded Product: 56523-59-2 This article mentions the following:

A series of CN-terminated alkanethiols were synthesized and used to generate self-assembled monolayers (SAMs) on gold. The SAMs were characterized using ellipsometry, contact angle goniometry, polarization modulation IR reflection absorption spectroscopy (PM-IRRAS), and XPS. The SAMs were compared to those derived from a series of analogous CH₃-terminated alkanethiols. The CN-terminated SAMs exhibited lower film thicknesses than the CH₃-terminated SAMs, which was largely due to their greater tilt angle on the surface. Addnl., the CN-terminated SAMs form well-ordered films on flat gold surfaces with relative packing densities being indistinguishable from the CH₃-terminated SAMs. The CN-terminated SAMs exhibited a less hydrophobic character than the SAMs derived from CH₃-terminated adsorbates, which was attributed to the dipole moment of the terminal group as well as the lone pair of the nitrogen atom of the CN-terminal group. In the experiment, the researchers used many compounds, for example, 15-Bromopentadecanoic acid (cas: 56523-59-2Recommanded Product: 56523-59-2).

15-Bromopentadecanoic acid (cas: 56523-59-2) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon闁艰京鐗梤omine bond is electrophilic in nature.

Stable Room-Temperature Molecular Negative Differential Resistance Based on Molecule-Electrode Interface Chemistry was written by Salomon, Adi;Arad-Yellin, Rina;Shanzer, Abraham;Karton, Amir;Cahen, David. And the article was included in Journal of the American Chemical Society in 2004.Formula: C15H29BrO2 This article mentions the following:

The authors show reproducible, stable neg. differential resistance (NDR) at room temperature in mol.-controlled, solvent-free devices, based on reversible changes in mol.-electrode interface properties. The active component is the cyclic disulfide end of mols. adsorbed onto Hg. As this active component is reduced, the Hg-mol. contact is broken, and an insulating barrier at the mol.-electrode interface is formed. Therefore, the alignment of the mol. energy levels, relative to the Fermi levels of the electrodes, is changed. This effect results in a decrease in the current with voltage increase as the reduction process progresses, leading to the so-called NDR behavior. The effect is reproducible and repeatable over >50 scans without any reduction in the current. The stability of the system, which is in the solid state except for the Hg, is due to the mol. design where long alkyl chains keep the mols. aligned with respect to the Hg electrode, even when they are not bound to it any longer. In the experiment, the researchers used many compounds, for example, 15-Bromopentadecanoic acid (cas: 56523-59-2Formula: C15H29BrO2).

15-Bromopentadecanoic acid (cas: 56523-59-2) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Formula: C15H29BrO2

New fluorescent indolium and quinolinium dyes for applications in aqueous halide sensing was written by Geddes, Chris D.;Douglas, Peter;Moore, Christopher P.;Wear, Trevor J.;Egerton, Peter L.. And the article was included in Dyes and Pigments in 1999.Electric Literature of C15H29BrO2 This article mentions the following:

Bromide and teraphenylborate salts of six new highly fluorescent dyes, produced by the reaction of two heterocyclic nitrogen bases (6-methoxyquinoline and harman) with 8-bromooctanoic acid, 11-bromoundecanoic acid, and 15-bromopentadecanoic acid have been prepared Unlike the bases themselves, the quaternary salts are water soluble and have fluorescence characteristics independent of pH in the range 7-11. Both the fluorescence intensity and fluorescence lifetime of these dyes are reduced in the presence of aqueous halide ions, allowing halide concentrations to be determined accurately at concentrations of importance to both medicine and industry. All the dyes have been characterized in terms of steady state fluorescence spectra and steady-state Stern-Volmer anal. The Stern-Volmer constants for the dyes are compared to those obtained for some com. available dyes. The prospects for using these dyes in halide sensor devices are discussed. In the experiment, the researchers used many compounds, for example, 15-Bromopentadecanoic acid (cas: 56523-59-2Electric Literature of C15H29BrO2).

15-Bromopentadecanoic acid (cas: 56523-59-2) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon鑱砨romine bond is electrophilic in nature. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Electric Literature of C15H29BrO2

Fluorescent indolium dyes for applications in aqueous halide sensing-part 2: the repeated alkylation of Harmane post quaternisation was written by Geddes, C. D.. And the article was included in Dyes and Pigments in 2001.Application In Synthesis of 15-Bromopentadecanoic acid This article mentions the following:

The repeated alkylation of harmane (1-methyl-9H-pyrido[3,4-b]indole) after quaternization has been observed during fusion with 8-bromooctanoic acid (I). This can be explained by two possible competing mechanisms, the electrophilic addition of carboxyalkylating agent to the resonance enamine form of the initial quaternized product and/or oligoester formation between the quaternized product and I. The mechanisms are supported by ¹H NMR, FTIR, and mass spectrometry anal., and by carboxyoctylation of 6-methoxyquinoline. The possibility for controlling the repeated alkylation in nanometer size silica pores, in essence restricted geometry nanometer size reaction vessels, is discussed. In the experiment, the researchers used many compounds, for example, 15-Bromopentadecanoic acid (cas: 56523-59-2Application In Synthesis of 15-Bromopentadecanoic acid).

15-Bromopentadecanoic acid (cas: 56523-59-2) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon閳ユ彽romine bond is electrophilic, i.e. alkyl bromides are alkylating agents. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.Application In Synthesis of 15-Bromopentadecanoic acid

Lipid composition, fatty acids and sterols in the seaweeds Ulva armoricana, and Solieria chordalis from Brittany (France): an analysis from nutritional, chemotaxonomic, and antiproliferative activity perspectives was written by Kendel, Melha;Wielgosz-Collin, Gaetane;Bertrand, Samuel;Roussakis, Christos;Bourgougnon, Nathalie;Bedoux, Gilles. And the article was included in Marine Drugs in 2015.Electric Literature of C15H29BrO2 This article mentions the following:

Lipids from the proliferative macroalgae Ulva armoricana (Chlorophyta) and Solieria chordalis (Rhodophyta) from Brittany, France, were investigated. The total content of lipids was 2.6% and 3.0% dry weight for U. armoricana and S. chordalis, resp. The main fractions of S. chordalis were neutral lipids (37%) and glycolipids (38%), whereas U. armoricana contained mostly neutral lipids (55%). Polyunsaturated fatty acids (PUFA) represented 29% and 15% of the total lipids in U. armoricana and S. chordalis, resp. In both studied algae, the phospholipids were composed of PUFA for 18%. In addition, PUFA were shown to represent 9% and 4.5% of glycolipids in U. armoricana and S. chordalis, resp. The essential PUFA were 16:4n-3, 18:4n-3, 18:2n-3, 18:2n-6, and 22:6n-3 in U. armoricana, and 20:4n-6 and 20:5n-3 in S. chordalis. It is important to notice that six 2-hydroxy-, three 3-hydroxy-, and two monounsaturated hydroxy fatty acids were also identified and may provide a chemotaxonomic basis for algae. These seaweeds contained interesting compounds such as squalene, 浼?tocopherol, cholest-4-en-3-one and phytosterols. The antiproliferative effect was evaluated in vitro on human non-small-cell bronchopulmonary carcinoma line (NSCLC-N6) with an IC₅₀ of 23 娓璯/mL for monogalactosyldiacylglycerols isolated from S. chordalis and 24 娓璯/mL for digalactosyldiacylglycerols from U. armoricana.

And the article was included in European Journal of Inorganic Chemistry in 2002.Quality Control of 15-Bromopentadecanoic acid This article mentions the following:

In an attempt to develop new technetium-based radiopharmaceuticals for the noninvasive diagnosis of myocardial metabolism, the authors synthesized three examples of novel metal-containing fatty acid derivatives according to the “3+1” mixed-ligand and the Schiff base/tricarbonyl design, Re:O[S(CH₂)₂S(CH₂)₂S][S(CH₂)₁₁S(CH₂)₄CO₂H] (7), Re:O[S(CH₂)₂NMe(CH₂)₂S][S(CH₂)₁₄CO₂H] (10) and ReBr(CO)₃[2-py-CH:N(CH₂)₁₁CO₂H] (14). The chelates contain the metal core in the oxidation states +5 (7 and 10) and +1 (14) and are attached to the end-position of a fatty acid chain. The complex formation was accomplished by ligand-exchange reactions with three different rhenium precursors, whereas the inactive rhenium metal was used as a surrogate of the technetium radionuclide. The mol. structures of the fatty acid complexes 7, 10 and 14 were determined by single-crystal x-ray diffraction analyses and impressively show a general problem in technetium tracer research, the significant structural alterations of bioactive mols. by coordination even to small metal chelates.

GC-MS analysis of fatty acids of Irvingia gabonensis seed fat was written by Okore, V. C.;Udeala, O. K.. And the article was included in Nigerian Journal of Natural Products and Medicine in 1997.Quality Control of 15-Bromopentadecanoic acid This article mentions the following:

Dika fat is the name given to the waxy material obtained from the seeds of Irvingia gabonensis (Fam. Irvingiaceae). The fat has been a subject of research in recent years, and it has been evaluated as a component of different drug delivery systems . Despite the impressive properties of this wax as have been established in the earlier studies, information on its chem. composition is rather scanty. Chem. characterization of the wax was done by GC-MS technique. The dika fat was obtained by solvent extraction, using the method described by Udeala et al (1980). A Fisons Trio 200 Quadrupole GC-MS instrument fitted with a 30m 鑴?0.32mm (i.d.) OV-1 capillary column, was used for the anal. The column temperature was programmed to rise from 100鎺矯 to 280鎺矯 at the rate of 5鎺?min. The carrier gas was helium flowing at the rate of 1.5ml/min. Ionization voltage of 70eV was applied. The solvent for dika fat was n-hexane. The identity of the components of dika fat was confirmed by a combination of computer-aided identification, the eight peak index of mas spectra as well as co-chromatog. The gas chromatogram of dika fat reveals seven peaks representing major components and about the same number of peaks for the minor components. In the experiment, the researchers used many compounds, for example, 15-Bromopentadecanoic acid (cas: 56523-59-2Quality Control of 15-Bromopentadecanoic acid).
