Wanted: Fluorochemical reference standards
When researchers discover a new chemical in the environment, they need a reference sample of known purity to do further research on the substance. Such reference standards are necessary to calculate concentrations of chemicals in environmental samples, conduct toxicology studies, or carry out environmental fate and transport testing.
But suppliers of chemical standards sometimes don’t have novel industrial chemicals, in particular those that are unintentional by-products of manufacturing processes. Researchers can measure the concentration of only some of the fluorochemicals in the Cape Fear River because they don’t have standards for comparison, says EPA scientist Mark Strynar.
Chemours supplied standards for the two Nafion by-products found in the Cape Fear River to Strynar in November. Strynar is seeking standards for perfluoro-3,5,7-trioxaoctanoic acid (PFO3OA), perfluoro-3,5-dioxahexanoic acid (PFO2HxA), and perfluoro-2-methoxyacetic acid (PFMOAA). “Those compounds need to be synthesized,” Strynar says. “Without that, our work is sort of at a standstill.”
“There’re people out there that can do that synthesis and they can make these available as chemicals for us to purchase,” Strynar says in a pitch to the chemistry community. “It doesn’t have to be 99.9% pure,” he says.
Strynar can be contacted at email@example.com.Gonna guess that Dr. Strynar could engage Apollo or Synquest for $20,000 or so, but what do I know?
