Usage

General Description

1H,1H,2H-Perfluorooctanal is a synthetic chemical compound that belongs to the class of perfluoroalkyl substances (PFAS). It is a colorless liquid with a strong, pungent odor. This chemical is used primarily as an intermediate in the production of fluorinated compounds, surfactants, and polymers. However, 1H,1H,2H-Perfluorooctanal is also used as a surfactant in firefighting foams and has been found to be a contaminant in the environment, including in water, soil, and air. It is considered to be a hazardous substance due to its persistence in the environment and potential for bioaccumulation, and it has been the subject of regulatory attention in various countries for its potential health and environmental risks.

A novel and simple synthetic route to perfluoroalkylacetaldehydes using commercially available alkali halides and metal oxides

Treatment of 1-acetoxy-1-iodo-2-perfluoroalkylethanes with aqueous alkali halides or neat metal oxides is presented as instead of via an innovative and highly accessible route to the synthesis of perfluoroalkylethanals. The reaction uses commercially available reactants and does not require the addition of any organic solvent.

Degradation of fluorotelomer alcohols: A likely atmospheric source of perfluorinated carboxylic acids

Human and animal tissues collected in urban and remote global locations contain persistent and bioaccumulative perfluorinated carboxylic acids (PFCAs). The source of PFCAs was previously unknown. Here we present smog chamber studies that indicate fluorotelomer alcohols (FTOHs) can degrade in the atmosphere to yield a homologous series of PFCAs. Atmospheric degradation of FTOHs is likely to contribute to the widespread dissemination of PFCAs. After their bioaccumulation potential is accounted for, the pattern of PFCAs yielded from FTOHs could account for the distinct contamination profile of PFCAs observed in arctic animals. Furthermore, polar bear liver was shown to contain predominately linear isomers (>99%) of perfluorononanoic acid (PFNA), while both branched and linear isomers were observed for perfluorooctanoic acid, strongly suggesting a sole input of PFNA from "telomer"-based products. The significance of the gas-phase peroxy radical cross reactions that produce PFCAs has not been recognized previously. Such reactions are expected to occur during the atmospheric degradation of all polyfluorinated materials, necessitating a reexamination of the environmental fate and impact of this important class of industrial chemicals.

Synthesis of 5-per(poly)fluoroalkyl-2,3-dihydro-1,4-diazepines

A series of 5-per(poly)fluoroalkyl-2,3-dihydro-1,4-diazepines were synthesized from α-per(poly)fluoroalkyl aldehydes and ethylenediamine. A possible reaction pathway was suggested.
