6:2/8:2diPAP Polyfluorinated Phosphate Esters (PAPs)

The application of polyfluorinated phosphate esters (PAPs) to food-contact paper products, as well as their subsequent detection in the environment, is well-known.  In fact, Wellington Laboratories offers multiple certified reference standrads based on the most commonly reported homologues of mono- and di-PAPs currently found in environmental ssmples based on published articles.  All of the disubstituted PAP standards that Wellington Laboratories currently offer are symmetrical, that is both polyfluorinated substituents have the same chain length. However, unsymmetrical diPAPs are also being reported.

In order to provide a more comprehensive line of diPAP products, wellington Laboratories has produced an unsymmetrical diPAP reference standard, specifically native sodium (1H,1H,2H,2H-perfluorooctyl-1H,1H,2H,2H-perfluorodecyl)phosphate (6:2/8:2diPAP).

Structure

Since PAPs can leach out of packaging materials and in to food that is consumed, it is important that they are accurately quantified in multiple matrices.  PAPs have also been identified as possible precursors to perfluoroalkylcarboxylic acids during biotransformation processes, therefore interest in these compounds is likely going to continue to be high.

PFCs are still emerging environmental contaminants and each of the groups compounds listed pose unique analytical challenges. In addition, the individual isomers, such as the branched PFOA and PFOS isomers are being found to have different toxicokinetic and ecokinetic properties. Thus Wellington's inventory of PFCs will continue to grow and we would urge you to visit our website, www.greyhoundchrom.com  for announcements of new products.
