With respect to acute toxicity, simple alcohols have low acute toxicities. Doses of several milliliters are tolerated. 647-42-7, formula is C8H5F13O, For pentanols, hexanols, octanols and longer alcohols, LD50 range from 2–5 g/kg (rats, oral). Ethanol is less acutely toxic.All alcohols are mild skin irritants. Computed Properties of 647-42-7
Zheng, Guomao;Salamova, Amina research published 《 Are Melamine and Its Derivatives the Alternatives for Per- and Polyfluoroalkyl Substance (PFAS) Fabric Treatments in Infant Clothes?》, the research content is summarized as follows. Per- and polyfluoroalkyl substances (PFAS) and melamine (MEL)-based compounds are used in textile finishing as grease, stain, and water repellents. Here, we investigated the occurrence of a large suite of PFAS and MEL compounds in 86 infant clothing items. The ∑MEL concentrations ranged from below the method detection limit to 250,000 ng/g with a median concentration of 78.2 ng/g, significantly higher (p < 0.05) than the ∑PFAS levels (1.22-203 ng/g; median 3.62 ng/g). MEL and its derivatives were most abundant in nylon clothes (median 32,800 ng/g), followed by organic cotton (median 6120 ng/g). In a simulated laundering experiment, the ∑MEL concentrations in clothing decreased on an average by ~60 and 90% when washed in cool (20°C) and warm (50°C) water, resp. This removal rate increased to 97% when the samples were washed with a detergent. The estimated daily intakes of MEL and PFAS through dermal absorption from nylon clothes were three orders of magnitude higher than those from the non-nylon clothes and decreased by more than half for washed clothes. Our findings demonstrate that MEL-based compounds are abundant in infant clothing and suggest that this group of compounds could be used as potential PFAS replacements in textile finishing.
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., Computed Properties of 647-42-7
