Formula: C16H34OIn 2022, Lin, Hang;Lv, Qiu-Bing;Wang, Hai-Feng;Zhao, Ke-Qing;Hu, Ping;Wang, Bi-Qin;Heinrich, Benoit;Donnio, Bertrand published 《Organic dyads and triads based on the triphenylene-rylenediimide couple: Molecular design, self-organization, and photo-physical properties》. 《Dyes and Pigments》published the findings. The article contains the following contents:

Liquid-crystalline D-A dyads and A-D-A triads, based on the chem. association of electron-donor (D) triphenylene discogens and electron-acceptor (A) perylene/benzoperylene diimides, have been synthesized by the Pd-catalyzed Sonogashira coupling/DBU-promoted cyclization reactions tandem. These mol. heterojunctions spontaneously self-organize into columnar hexagonal (Col_hex) or/and rectangular (Col_rec) mesophases, over broad temperature ranges including room temperature, with the antagonist moieties segregated into alternated homo-mol. (homolithic) stacks within mixed columns. Their intramol. electron and energy transfers have been studied by UV/Vis absorption and fluorescence emission spectroscopies. Due to photo-induced electron transfer between donor and acceptor units, fluorescence quenching is systematically observed for all the dyads and triads. This study further reveals that perylenediimide is a stronger electron acceptor than the larger benzoperylenediimide building block. D. function theory calculations of their mol. structures and HOMO-LUMO energy levels and gaps support the exptl. results and demonstrate that these donor-acceptor systems have potential applications in various optoelectronic devices.2-Hexyl-1-decanol (cas: 2425-77-6) were involved in the experimental procedure.

Islam, Rafiquel;Melvin, Steven D.;Kit Yu, Richard Man;O’Connor, Wayne A.;Anh Tran, Thi Kim;Andrew-Priestley, Megan;Leusch, Frederic D. L.;MacFarlane, Geoff R. published 《Estrogenic mixtures induce alterations in lipidomic profiles in the gonads of female oysters》. The research results were published in《Chemosphere》 in 2022.Computed Properties of C14H22O The article conveys some information:

This study aimed to reveal possible alterations to lipidomic profiles in Sydney rock oysters, Saccostrea glomerata, exposed to estrogenic mixtures (i.e., estrone, E1; 17β-estradiol, E2; estriol, E3; 17α-ethinylestradiol, EE2; bisphenol A, BPA; 4-t-octylphenol, 4-t-OP; and 4-nonylphenol, 4-NP) at “low” and “high” concentrations, typical of those detected in Australian and global receiving waters. A seven-day acute exposure window exhibited significantly lower abundances of many non-polar metabolites in digestive gland, gills, and gonads. Overall, there was a strong effect of the carrier solvent ethanol (despite a low exposure of 0.0002%), with all solvent containing treatments exhibiting lower abundances of lipidic metabolites, especially in the gill and digestive gland. No significant changes of the lipidome were exhibited in the male gonad by estrogenic exposure. However, in the female gonad, significant reductions of phospholipids and phosphatidylcholine were associated with exposure to high estrogenic mixtures We hypothesise that the decreases in these phospholipids in the female gonad may be attributable to (1) lower algal consumption and thus lower uptake of lipidic building blocks; (2) a reduction of available substrates for phospholipid and phosphatidylcholine synthesis; and/or (3) induction of reactive oxygen species via estrogen metabolism, which may cause lipid peroxidation and lower abundance of phospholipids. The experimental procedure involved many compounds, such as 4-tert-Octylphenol (cas: 140-66-9) .

4-tert-Octylphenol(cas: 140-66-9) has been used as a reference standard for the determination of the analyte in water samples using ultra-high-performance liquid chromatography/tandem mass spectrometry (UHPLC/MS/MS).Computed Properties of C14H22O

Giamaki, Despoina;Dindini, Konstantina;Samanidou, Victoria F.;Touraki, Maria published 《Simultaneous Quantification of Bisphenol-A and 4-Tert-Octylphenol in the Live Aquaculture Feed Artemia franciscana and in Its Culture Medium Using HPLC-DAD》 in 2022. The article was appeared in 《Methods and Protocols》. They have made some progress in their research.COA of Formula: C14H22O The article mentions the following:

Aquaculture, a mass supplier of seafood, relies on plastic materials that may contain the endocrine disruptors bisphenol-A (BPA) and tert-octylphenol (t-OCT). These pollutants present toxicity to Artemia, the live aquaculture feed, and are transferred through it to the larval stages of the cultured organisms. The purpose of this work is the development and validation of an anal. method to determine BPA and t-OCT in Artemia and their culture medium, using n-octylphenol as the internal standard Extraction of the samples was performed with H2O/TFA (0.08%)-methanol (3:1), followed by SPE. Anal. was performed in a Nucleosil column with mobile phases A (95:5, volume/volume, 0.1% TFA in H2O:CH3CN) and B (5:95, volume/volume, 0.08% TFA in H2O:CH3CN). Calibration curves were constructed in the range of concentrations expected following a 24 h administration of BPA (10 μg/mL) or t-OCT (0.5 μg/mL), below their resp. LC50. At the end of exposure to the pollutants, their total levels appeared reduced by about 32% for BPA and 35% for t-OCT, and this reduction could not be accounted for by photodegradation (9-19%). The developed method was validated in terms of linearity, accuracy, and precision, demonstrating the uptake of BPA and t-OCT in Artemia. And 4-tert-Octylphenol (cas: 140-66-9) was used in the research process.

4-tert-Octylphenol(cas: 140-66-9) is a common environmental pollutant showing weak estrogenic effects.COA of Formula: C14H22O It has been shown to cause harm to vertebrate male reproductive systems.

The author mentioned the following in the article:

An improved approach was developed to obtain essential oil from Thlaspi arvense L. leaves (TAL) and seeds (TAS) using microwave-assisted hydrodistillation and extraction in situ by vegetable oil. Some potential parameters that affected the yield of essential oils were systematically investigated. Under the obtained optimization conditions, the maximized yields of TAL and TAS essential oils were 0.77 ± 0.02 mg/g and 2.69 ± 0.08 mg/g, resp. The results analyzed by GC-MS revealed that the main component of TAS essential oil was allyl isothiocyanate (AITC), which accounted for 44.69% of the total essential oil content. The proportion of AITC in TAL essential oil, however, was only 9.66%. Results showed that they all had significant inhibition on P. expansum, with AITC exhibiting the greatest inhibition on P. expansum. The study of antifungal activity indicates that AITC has potential application value and broad application prospects in food preservation-related fields in the future.2-Hexyl-1-decanol (cas: 2425-77-6) were involved in the experimental procedure.

Synthetic Route of C16H34O《Chemical characterization in hydraulic fracturing flowback and produced water (HF-FPW) of shale gas in Sichuan of China》 was published in 2020. The authors were Wang, Bing;Xiong, Mingyang;Wang, Peijie;Shi, Bin, and the article was included in《Environmental Science and Pollution Research》. The author mentioned the following in the article:

Abstract: Large amounts of fracturing flowback and wastewater with complex compositions are produced during hydraulic fracturing. Characterization of hydraulic fracturing flowback and produced water (HF-FPW) is an important initial step in efforts to determine a suitable treatment method for this type of wastewater. In the present study, fracturing flowback and produced water samples were obtained from well CN-F and well CN-E in the prophase and anaphase stages of the Changning shale gas mining area. Chem. characterization of inorganic and organic substances was then conducted. Metal contents were determined by inductively coupled plasma optical emission spectroscopy (ICP-OES), and all inorganic anions involved were determined by ion chromatog. The organic pollutant components were analyzed in detail by combining Fourier transform IR spectrometer (FTIR) and gas chromatog.-mass spectrometer (GC-MS). Results showed that samples contained salt (TDS = 30,000-50,000 mg/L), metals (e.g., 650 ± 50 mg/L calcium), and total organic carbon (TOC = 32-178 mg/L). The organic substances detected in all samples could be divided into six categories, alkanes, aromatics, halogenated hydrocarbons, alcs., esters, and ketones. C6-C21 straight-chain alkanes and C7-C13 naphthenes had the highest amount of organic matter, reaching more than 48%. The organic matter contained fracturing fluid additives, such as surfactants (e.g., ethylene glycol), and nitrotrichloromethane, which is a chlorinated product of some additives. These results provide information on the chem. composition of HF-FPW in Sichuan, China, as well as a basis for subsequent processing. And 2-Hexyl-1-decanol (cas: 2425-77-6) was used in the research process.

Watanabe, Michiko;Sasaki, Takamitsu;Takeshita, Jun-ichi;Kushida, Madoka;Shimizu, Yuki;Oki, Hitomi;Kitsunai, Yoko;Nakayama, Haruka;Saruhashi, Hitomi;Ogura, Rui;Shizu, Ryota;Hosaka, Takuomi;Yoshinari, Kouichi published 《Application of cytochrome P450 reactivity on the characterization of chemical compounds and its association with repeated-dose toxicity》. The research results were published in《Toxicology and Applied Pharmacology》 in 2020.Product Details of 599-64-4 The article conveys some information:

Repeated-dose toxicity (RDT) studies are one of the critical studies to assess chem. safety. There have been some studies attempting to predict RDT endpoints based on chem. substructures, but it remains very difficult to establish such a method, and a more detailed characterization of chem. compounds seems necessary. Cytochrome P450s (P450s) comprise multiple forms with different substrate specificities and play important roles in both the detoxification and metabolic activation of xenobiotics. In this study, we investigated possible use of P 450 reactivity of chem. compounds to classify the compounds A total of 148 compounds with available rat RDT test data were used as test compounds and subjected to inhibition assays against 18 human and rat P450s. Among the tested compounds, 82 compounds inhibited at least one P 450 form. Hierarchical clustering analyses using the P 450 inhibitory profiles divided the 82 compounds into nine groups, some of which showed characteristic chem. and biol. properties. Principal component analyses of the P 450 inhibition data in combination with the calculated chem. descriptors demonstrated that P 450 inhibition data were plotted differently than most chem. descriptors in the loading plots. Finally, association analyses between P 450 inhibition and RDT endpoints showed that some endpoints related to the liver, kidney and hematol. were significantly associated with the inhibition of some P450s. Our present results suggest that the P 450 reactivity profiles can be used as novel descriptors for characterizing chem. compounds for the investigation of the toxicity mechanism and/or the establishment of a toxicity prediction model. And 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) was used in the research process.

The article was appeared in 《Organic Letters》. They have made some progress in their research.Electric Literature of C14H14O2 The article mentions the following:

A novel palladium-catalyzed alkene diacetoxylation with dioxygen (O₂) as both the sole oxidant and oxygen source is developed, which was identified by ¹⁸O-isotope labeling studies. Control experiments suggested that bis(pinacolato)diboron (B₂pin₂) played a dominant intermediary role in the formation of a C-O bond. This method displayed good functional group tolerance with moderate to excellent yields and could be successfully applied to the late-stage modification of natural products. Furthermore, an atm. pressure of dioxygen enhances the practicability of the protocol. To complete the study, the researchers used rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) .

Chinese people have consistentlypreferred high mountain tea because specific flavors are memorable for them, and also, people have traditionally considered this type of tea to be good for health. Tieguanyin is one of the famous traditional Chinese tea that has ever-changing aromas. To illustrate the various characteristics in volatile fragment compounds from Tieguanyin tea, fresh tea leaves collected from different elevations (450, 650, and 900 m) were detected using GC-MS by solid-liquid extraction The results showed that volatile aromatic compounds, such as benzyl alc., Ph ethanol, and acetophenone, were the most abundant in tea leaves located with high elevation. Meanwhile, 1-hexanol, 1-nananol, and nanoic acid, as a type of aliphatic aroma, were more prevalent in low-elevation tea orchards. Catechols and alkaloids are largely cumulated in low- and high-elevation tea leaves, resp. Our findings also showed that elemene was widely consisted of high-elevation tea metabolites. It provided practicality for the preparation of tea manufacturing in major Tieguanyin tea-producing regions. And 2-Hexyl-1-decanol (cas: 2425-77-6) was used in the research process.
