Description

Hexacosafluorododecane (CAS 307-59-5) is a high-purity perfluorinated alkane with the molecular formula C₁₂F₂₆. This fully fluorinated dodecane derivative, also known as Perfluorododecane, exhibits exceptional chemical inertness, thermal stability, and hydrophobic/oleophobic properties due to its strong carbon-fluorine bonds. As a member of the perfluoroalkane family, it is characterized by its non-reactive nature, low surface energy, and resistance to solvents, acids, and bases. Ideal for advanced material science applications, this compound is supplied as a clear, colorless liquid or low-melting solid with high purity (>98%) to ensure consistency in research and industrial processes. Suitable for use as a reference standard, dielectric fluid, or additive in specialty coatings and lubricants where extreme conditions are encountered.

Application

Hexacosafluorododecane is widely utilized as a dielectric fluid in high-voltage equipment due to its exceptional electrical insulation properties. It serves as a hydrophobic/oleophobic coating additive for textiles, electronics, and aerospace materials to impart water and oil repellency. Researchers also employ it as a reference standard in analytical chemistry and environmental studies tracking perfluoroalkyl substances (PFAS).
