Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 647-42-7, formula is C8H5F13O, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , HPLC of Formula: 647-42-7
Ayala-Cabrera, J. F.;Contreras-Llin, A.;Moyano, E.;Santos, F. J. research published 《 A novel methodology for the determination of neutral perfluoroalkyl and polyfluoroalkyl substances in water by gas chromatography-atmospheric pressure photoionization-high resolution mass spectrometry》, the research content is summarized as follows. Here, we developed and validated a new gas chromatog.-atm. pressure photoionization-high-resolution mass spectrometry (GC-APPI-HRMS) method combined with headspace solid-phase microextraction (HS-SPME) for the determination of neutral perfluoroalkyl and polyfluoroalkyl substances (PFASs) in water samples. The method includes fluorotelomer olefins (FTOs), fluorotelomer alcs. (FTOHs), fluoroctanesulfonamides (FOSAs) and sulfonamido-ethanols (FOSEs). The feasibility of the GC-APPI interface for the ionization of the target compounds was evaluated, achieving the best results using neg.-ion dopant-assisted ionization with acetone and a source and capillary temperatures of 225°C and 175°C, resp. Under optimal conditions, FTOs and FTOHs mass spectra showed intense in-source CID fragment ions from the fluoroalkyl chain but also the superoxide [M+O2]-• adduct ion. For FOSAs, [M-H]– was the main ion generated, while FOSEs mass spectra showed fragment ions corresponding to the different cleavages of the functional group. The high ionization efficiency achieved with the GC-APPI interface provided limits of the detection lower than those obtained using traditional GC-MS ionization techniques, with a high sensitivity, selectivity and precision. For water anal., a fast and simple HS-SPME procedure was developed, avoiding evaporation steps, which could lead to the loss of the most volatile compounds The developed HS-SPME GC-APPI-HRMS method showed a good anal. performance for the anal. of river water samples, providing very low limits of detection (0.02-15 ng L-1), good repeatability (RSD < 11%) and trueness (relative error < 12%).
HPLC of Formula: 647-42-7, 3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctan-1-ol, also known as 1H,1H, 2H, 2H-Tridecafluoro-1-n-octanol , is a useful research compound. Its molecular formula is C8H5F13O and its molecular weight is 364.1 g/mol. The purity is usually 95%.
1H,1H, 2H, 2H-Tridecafluoro-1-n-octanol is a material used to improve nanotube composites. It is also used in the synthesis of a recyclable fluorous hydrazine carbothioate compound with NCS to catalyze the acetalization of aldehydes.
1H,1H,2H,2H-Tridecafluoro-1-n-octanol is a potent and selective halogenated hydrocarbon. It binds to DNA at the dinucleotide phosphate site, which is an important site for polymerase chain reaction (PCR) activation. 1HFN has been shown to be more effective than other halogenated hydrocarbons in vitro assays on rat liver microsomes. It has been used as an additive in wastewater treatment to remove organic contaminants and metal ions. In vivo studies have been carried out in CD-1 mice to determine the effects of 1HFN on the liver and kidneys; these studies showed no toxicological effects on these organs. 1HFN also has been shown to inhibit enzymes such as cytochrome P450 and monoamine oxidase B that are involved in drug metabolism and may lead to adverse reactions with drugs metabolized by these enzymes., 647-42-7.
