Description

3,3,4,4,5,5,6,6,7,7,8,8,9,10,10,10-Hexadecafluoro-9-(Trifluoromethyl)Decyl Dihydrogen Phosphate is a highly fluorinated phosphate ester, a specialty organofluorine compound prized for its unique combination of surface-active properties and chemical stability. This compound is critical for applications requiring materials with extreme hydrophobicity, oleophobicity, and resistance to harsh chemical environments. It is primarily sought by R&D and manufacturing sectors in advanced materials science, including the development of high-performance coatings, surfactants, and specialty polymers.

Application

• Fluorinated Surfactants & Additives: Serves as a key intermediate for synthesizing high-performance surfactants used in demanding applications like fire-fighting foams (AFFF), coatings, and electronics.
• Surface Modification Agents: Used to impart permanent water- and oil-repellent (stain-resistant) properties to textiles, leather, paper, and non-woven fabrics.
• Specialty Polymer Synthesis: Acts as a monomer or additive in the production of fluorinated polymers and copolymers, enhancing their chemical resistance, thermal stability, and surface characteristics.
• Advanced Material Coatings: Employed in formulating anti-fouling, anti-graffiti, and corrosion-resistant coatings for industrial, marine, and architectural applications.
• Lithium-Ion Battery Electrolytes: Investigated as a potential electrolyte additive to improve the stability and safety of high-voltage battery systems.
• Pharmaceutical & AgroChemical Intermediates: Utilized in the synthesis of fluorinated bioactive molecules, where the introduction of fluorine atoms can dramatically alter metabolic stability and activity.
