Description

2,2,3,3,4,4,5,5,6,6,7,7-Dodecafluorooctanedioic acid (CAS No. 678-45-5) is a highly fluorinated dicarboxylic acid with the molecular formula C₈H₂F₁₂O₄. This compound, also known as Dodecafluorosuberic acid or Perfluorosuberic acid, features a fully fluorinated carbon backbone, imparting exceptional chemical stability, hydrophobicity, and resistance to harsh environments. Its unique structure makes it valuable in advanced material science, particularly for surface modification, polymer synthesis, and as a building block for fluorinated surfactants. The high electronegativity of fluorine atoms enhances its reactivity in esterification and amidation reactions, enabling the creation of specialized fluorinated derivatives. Available in high purity grades (≥98%), this product is ideal for researchers developing fluoropolymers, coatings, or biomedical applications requiring inert, low-surface-energy materials. Proper handling with PPE is recommended due to potential irritant properties.

Application

This fluorinated diacid serves as a key intermediate in synthesizing fluorinated polymers with enhanced thermal and chemical resistance, suitable for aerospace or semiconductor coatings. Its hydrophobic properties make it useful in creating water-repellent surfaces or anti-fouling materials. Researchers also employ it to develop fluorosurfactants for firefighting foams or as a modifier for biomedical implants requiring bio-inert surfaces.
