Description

Decafluorobiphenyl (CAS No. 434-90-2) is a highly fluorinated aromatic compound with the molecular formula C₁₂F₁₀. This perfluorinated derivative of biphenyl exhibits exceptional thermal stability, chemical inertness, and hydrophobic properties, making it a valuable reagent in advanced synthetic and material science applications. Its IUPAC name, 1,2,3,4,5-pentafluoro-6-(2,3,4,5,6-pentafluorophenyl)benzene, reflects its symmetrical structure with ten fluorine atoms substituting all hydrogen positions. Available in high purity grades (≥98%), it is supplied as a white crystalline solid with minimal moisture sensitivity. Ideal for use as a fluorinated building block, crosslinking agent, or precursor for specialty polymers, Decafluorobiphenyl is packaged under inert gas to ensure stability and shipped with detailed analytical certificates (GC/MS, NMR).

Application

Decafluorobiphenyl is widely utilized as a key intermediate in the synthesis of fluorinated polymers, liquid crystals, and electronic materials due to its electron-deficient aromatic system. It serves as a crosslinker in high-performance elastomers and coatings, enhancing resistance to heat, chemicals, and UV degradation. Researchers also employ it in organic electronics, such as perovskite solar cells, to improve charge transport properties and device stability.
