Hexafluorobisphenol A, identified by CAS number 1478-61-1, is an organofluorine compound that has garnered significant attention across multiple industrial sectors due to its unique chemical properties and diverse applications. Understanding its chemistry is fundamental for researchers and manufacturers aiming to leverage its potential.

Chemically, Hexafluorobisphenol A is a derivative of bisphenol A, where the methyl hydrogens on the isopropylidene bridge are replaced by fluorine atoms. This structural modification, specifically the presence of the -CF3 groups, imparts distinct characteristics. Its molecular formula is C15H10F6O2, and it typically presents as a white to pale beige powder. Key physical properties include a melting point of 160-163 °C and a boiling point of 400 °C. It exhibits low solubility in water but is soluble in solvents like DMSO and methanol.

The primary industrial application for Hexafluorobisphenol A is its use as a vulcanization accelerator (often denoted as FF34) in the production of fluororubbers. In this role, it facilitates the cross-linking process, leading to vulcanized rubber that exhibits superior permanent deformation resistance and enhanced tensile strength. These properties are critical for elastomers used in demanding environments where reliability and durability are paramount.

Furthermore, Hexafluorobisphenol A serves as a valuable intermediate in the pharmaceutical industry. Its fluorinated structure can be strategically employed in the synthesis of various pharmaceutical compounds, contributing unique properties to potential drug candidates. This dual utility underscores its importance as a versatile chemical building block.

For businesses seeking to acquire Hexafluorobisphenol A, understanding these properties is essential for making informed purchasing decisions. Sourcing from reputable manufacturers and suppliers, particularly those in China known for their chemical expertise, ensures access to high-purity product (≥99.5%) crucial for both fluororubber enhancement and pharmaceutical synthesis. Companies looking to buy this chemical should request detailed specifications and competitive quotes to secure their supply chain.
