And the article was included in Xiandai Shipin Keji in 2017.COA of Formula: C12H22O4 This article mentions the following:

The essential oil was extracted from the dried twigs and leaves of Spiraea mongolica Maxim by hydro-distillation and identified by GC-MS. The main compositions of the oil were fatty acids and their derivatives, Et palmitate (38.631%), Et linolelaidate (23.576%) and Et linolenate (14.634%). From the dried twigs and leaves, botulin (1), lupine-3,20-diol (2), 1灏?hydroxyl-6,9-dien-8-oxoeremophil-11-nor-11-ketone (3), 3-(4-Methoxyphenyl) propanal (4), stigmasterol (5), 灏?Sitosterol (6) were isolated by silica gel column chromatog. and identified by NMR data. Their DPPH free radical scavenging and antimicrobial activities were sep. evaluated. The essential oil showed good to moderate DPPH free radical scavenging activity (IC₅₀=900 娓璯/mL), while had no apparent antimicrobial activity. Compound (4) exhibited reasonably strong DPPH free radical scavenging ability (IC₅₀=13 娓璯/mL) and showed diverse antimicrobial competence against Aspergillus flavus, Bacillus subtilis and Candida albicans. Compound (3) showed antimicrobial activity against Aspergillus flavus, Bacillus subtilis and weak DPPH free radical scavenging activity. These results of the study had certain significance in the study of traditional Chinese medicine plant and development of new drugs. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6COA of Formula: C12H22O4).

Dimethyl decanedioate (cas: 106-79-6) 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. 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.COA of Formula: C12H22O4

Evaluation of carbon mineralization and structural alterations of organic carbon in high-moor peat soils during incubation was written by Sazawa, Kazuto;Kubota, Daiki;Yoshida, Hironori;Hata, Noriko;Wada, Naoya;Kuramitz, Hideki. And the article was included in Journal of Soils and Sediments in 2020.Recommanded Product: 106-79-6 This article mentions the following:

The quantity and quality of soil organic matter (SOM) in the wetlands and peatlands are important for evaluating of the effects of environmental changes. This study’s aim was to evaluate the change in the chem. properties of SOM and dissolved organic matter (DOM) during a constant temperature incubation of high-moor peat soil under two types of vegetation. Incubation of high-moor peat soils collected from marsh vegetation and dwarf bamboo was conducted for 108 days at each temperature of 25鎺矯 and 35鎺矯. The chem. properties of alk. extract and DOM in soil samples during incubation were analyzed by tetramethylammonium hydroxide thermochemolysis-gas chromatog.-mass spectrometry (TMAH-GC/MS) and fluorescence anal. The cumulative CO₂ emission from peat under dwarf bamboo was higher than that of peat under marsh vegetation. During incubation at 35鎺矯, plant and microbial residues in DOM extracted from dwarf bamboo soil were increased significantly at the early stages of culture. On the other hand, the components of DOM in the marsh vegetation soil sample did not significantly change between incubation at each temperature The fluorescence spectra showed that protein-like fluorescent DOM contained in dwarf bamboo soil is consumed by microorganisms, which promotes leaching of humic-like fluorescent DOM and carbon mineralization during the incubation period at a higher temperature Compared with marsh vegetation soil, the DOM in dwarf bamboo soil is susceptible to temperature rises and can be a larger source of CO₂ emissions. This study shows that evaluation of DOM properties in soil could be useful to assess the effect of climate change on soil environment. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Recommanded Product: 106-79-6).

Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters contain a carbonyl center, which gives rise to 120鎺?C閳ユ弲閳ユ彊 and O閳ユ弲閳ユ彊 angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C閳ユ彊閳ユ弲 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.

Electron-transporting semi-rigid polyester-imides made up of a tetracarboxdiimide of p-terphenyl analogue of 1,3,4-oxadiazole: Preparation, and thermal, optical, and electrochemical properties was written by Sato, Moriyuki;Inata, Mutsumi;Yamaguchi, Isao. And the article was included in Journal of Applied Polymer Science in 2012.Application of 106-79-6 This article mentions the following:

Electron-transporting semi-rigid polyester-imides composed of a tetracarboxdiimide (2,5-di(3,4-dicarboxphthalimido)-1,3,4-oxadiazole; DDPOD) of p-terphenyl analog of 1,3,4-oxadiazole were successfully prepared by the melt polycondensation of a monomer, a dialc. derivative of DDPOD, with four diesters in the presence of zinc acetate as a catalyst, and their thermal, UV-vis absorption, photoluminescent (PL) and electrochem. properties were examined The structures of the resulting polymers were characterized by Fourier transform IR and ¹H NMR spectroscopies and elemental analyses. Differential scanning calorimetry measurements, X-ray diffraction analyses and polarizing microscope observations suggested that the polymers prepared from aliphatic diesters formed highly ordered thermotropic liquid crystalline smectic phases. The UV-vis and PL spectra in the solutions and in the films displayed that the obtained polymers showed absorption and bluish violet-light emissions based on the DDPOD moiety. Cyclic voltammetry measurements revealed that these polymers had more stable HOMO levels and were more sensitive to oxidation than polymers comprising electron-accepting 2,5-diphenyl-1,3,4-oxadiazole in the backbones. The DDPOD unit brought the extension of differences between electron-injection and hole-injection barriers in the polymers. It was found that the polymers containing the DDPOD unit in the main chains in this study not only showed bluish violet light-emitting properties but also behaved as electron-transporting materials for organic electroluminescent devices. 婕?2012 Wiley Periodicals, Inc.

Comparative analysis of eastern and western drying-oil binding media used in polychromic artworks by pyrolysis-gas chromatography/mass spectrometry under the influence of pigments was written by Wang, Na;He, Ling;Zhao, Xiang;Simon, Stefan. And the article was included in Microchemical Journal in 2015.Product Details of 106-79-6 This article mentions the following:

The mostly used drying-oils as binding media in historical artworks of eastern tung-oil and western linseed-oil, poppy-oil, walnut-oil are comparatively identified by online methylated pyrolysis-gas chromatog./mass spectrometry (Py-GC/MS). Based on the anal. of un-pigmented and pigmented reference samples after treated by natural aging, hydro-thermal aging and UV aging, resp., the characteristic pyrolysis products of all drying-oils are classed into mono-carboxylic acids (C6-8, 14, 16, 18, 20), di-carboxylic acids (2C6-12), glycerol, erythritol, 2-tridecanone, 8-hydroxy-octanoic acid, 3-octyl-oxiraneoctanoic acid and 2,6,10-trimethyl-9-undecenoic acid. Both benzene derivative and 9,10-dihydroxy-octadecanoic acid are suggested as the marked components for distinguishing eastern and western drying-oil. The investigated pigments of malachite, cinnabar, azurite and ochre do not show obvious influence on the detection of characteristic pyrolysis products of drying-oil, but they are proved to accelerate the aging and hydrolyzing rate of drying-oil, especially the pigment of cinnabar. The established online methylated Py-GC/MS procedure and the summarized data have been successfully applied on the identification of raw tung-oil and boiled tung-oil in historical painting samples collected from Drum Tower (Ming Dynasty), Bell Tower (Ming Dynasty), and Thousand-Buddha Cliff Grotto (Tang Dynasty). It is believed that the established Py-GC/MS procedure is able to provide wide application in archeol. research.

Stratigraphic Examination of a Korean Lacquered Wooden Coffin Sample by Pyrolysis/GC/MS was written by Park, Jongseo;Schilling, Michael R.;Khanjian, Herant;Lee, Jiyoung. And the article was included in Chromatographia in 2018.Formula: C12H22O4 This article mentions the following:

A lacquered wooden coffin decorated with gilded Sanskrit letters excavated in the Nongso ancient tomb site was constructed around the fourteenth century in Korea. Pyrolysis/gas chromatog./mass spectrometry was employed to identify the materials of the lacquered surface by analyzing the individual layers. The components of lacquer were detected in all four layers of wood substrate, black, brown, and gilded layers, indicating the coating material was Asian lacquer. The wood seems to be a kind of pine tree from the observation that pine resin-related components were detected in much of the wood substrate and decreasing in the upward direction. Markers of drying oil like azelaic acid and palmitic acid existed in large quantities in the black, brown, and gilded layers, indicating that drying oil was intentionally added to give a luster. In addition, compared with dried Asian lacquer from Korea, the lacquer used in the coffin was determined to be of the same type. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Formula: C12H22O4).

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.Formula: C12H22O4

An efficient synthetic method was developed for the preparation of 1-octacosanol (C₂₈-alc., long-chain aliphatic alc., higher alc.) (I) from com. available lipid-based intermediates namely sebacic acid (decanedioic acid) and stearyl alc. (1-octadecanol). The key step in the synthesis was a Wittig reaction. This product on simultaneous hydrogenation of double bond and deprotection of tert-butyldimethylsilyl protecting group in a single step on treatment with Pd/C and H₂ in methanol at ambient temperature resulted octacosanol in 95% yields. The products were characterized by IR, ¹H NMR, and GC-MS anal. The synthesis of the target compound was achieved by a Wittig reaction of (octadecyl)triphenylphosphonium bromide with 10-[[(1,1-dimethylethyl)dimethylsilyl]oxy]decanal, formation of an alkene and subsequent reduction In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Application of 106-79-6).

Dimethyl decanedioate (cas: 106-79-6) 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 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.
