Biological and Chemical Action

Whereas BPA binds with human estrogen-related receptor gamma (ERR-γ), BPAF all but ignores ERR-γ. Instead, BPAF activates ERR-α and binds to and disables ERR-β.[2]

The chemical shifts in ¹H, ¹³C and ¹⁹F NMR spectroscopy are given in the literature.[3]

Applications

Bisphenol AF is used as a crosslinking agent for certain fluoroelastomers and as a monomer for polyimides, polyamides, polyesters, polycarbonate copolymers and other specialty polymers. Polymers containing Bisphenol AF are useful in specialties such as high-temperature composites and electronic materials. Industries include cosmetics, chemical manufacturing, production of metals and rubber. It can also be a plastic additive.[4]
