Description

(3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooct-1-Yl)Phosphonic Acid is a high-value fluorinated phosphonic acid derivative, prized for its unique combination of a hydrophobic, oleophobic perfluoroalkyl chain and a reactive phosphonic acid head group. This structure makes it an exceptional surface-modifying agent, providing durable, low-surface-energy coatings and enhancing material compatibility. It is essential for manufacturers and R&D chemists in advanced materials, electronics, and specialty chemical synthesis who require precise control over surface properties and chemical functionality.

Application

• Surface Modification Agent: Used to create self-assembled monolayers (SAMs) on metal oxides (e.g., aluminum, titanium, stainless steel) for corrosion resistance, improved adhesion, and hydrophobicity.
• Textile & Leather Treatment: Imparts durable oil, water, and stain repellency to fabrics, carpets, and leather goods.
• Electronics & Semiconductor Industry: Serves as a key intermediate for synthesizing fluorinated compounds used in photoresists, anti-reflective coatings, and as adhesion promoters in microelectronics.
• Specialty Polymer Additive: Incorporated into polymers and resins to enhance surface properties, reduce friction, and improve chemical resistance.
• Biomedical Materials: Used to modify the surface of medical devices and implants to reduce protein adsorption and improve biocompatibility.
• Catalyst & Ligand Synthesis: Acts as a precursor for creating specialized ligands in catalysis and metal-organic frameworks (MOFs).
