Description

Perfluorononanoic acid (PFNA) is a synthetic, fully fluorinated organic compound with the molecular formula C₉HF₁₇O₂. This high-purity fluorochemical is characterized by its strong carbon-fluorine bonds, which impart exceptional thermal and chemical stability. As a perfluorinated carboxylic acid, PFNA exhibits unique surfactant properties and hydrophobic/lipophobic characteristics that make it valuable for specialized industrial and research applications.

The compound is supplied as a white to off-white crystalline solid with excellent batch-to-batch consistency. Our rigorous quality control ensures optimal performance in demanding applications. PFNA is packaged under inert conditions to maintain stability and purity during storage and transport.

This product is particularly useful in materials science and surface modification applications where its perfluorinated chain length provides distinct advantages over shorter-chain alternatives. Researchers will appreciate the compound’s well-characterized properties and reliable performance in experimental systems.
