Hexafluorobisphenol A CAS 1478-61-1 Bisphenol AF

Bisphenol AF is also known as hexafluorobisphenol A, 2,2-bis(4-hydroxyphenyl)hexafluoropropane, referred to as BPAF, also known as polycarbonate in industry, and is mostly used in the production of shatterproof plastics. It is slightly soluble in carbon tetrachloride, hardly soluble in water, easily soluble in ethanol, acetone, ether, toluene and other organic solvents and strong alkali solutions. Bisphenol AF can decompose and burn when heated to 510°C. BPA is one of the most widely used industrial compounds in the world, used in the manufacture of food packaging materials, medical devices, baby bottles, water bottles, eyeglass lenses and hundreds of other everyday products.

Bisphenol AF dissolves in dilute alkali to generate corresponding metal salts, which can undergo nitration reaction, nitrosation reaction, Friedel-Crafts alkyl substitution reaction, halogenation reaction, carboxylation reaction, esterification reaction, and can be condensed with acetone to form polyphenol. Excess formaldehyde condenses in alkaline medium to generate phenolic resin, and condenses with fatty alcohol, epoxy polymer, epichlorohydrin, etc. to generate corresponding ether.

BPA is likely to migrate from containers or packaging materials into food and beverages after exposure to heat, and many studies have shown that exposure to BPA may affect neurological development and immune system function, especially in infants and young children. BPA can also simulate female hormones, disrupt the endocrine system, and may cause fertility problems, precocious puberty, affect breast development and reproductive function, and even cause various hormone-related cancers. With the occurrence of various research results and adverse events of bisphenol A, such as the “baby bottle containing bisphenol A” incident, many countries and regions have established strict control standards for bisphenol A.
