Description

n-Ethyl-1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-Pentadecafluoro-n-(2-Hydroxyethyl)Heptane-1-Sulphonamide is a high-performance fluorinated sulphonamide derivative, engineered to impart exceptional surface activity and chemical resistance. This compound matters because it combines the oil- and water-repellent properties of a long perfluoroalkyl chain with the reactive functionality of a sulphonamide and a terminal hydroxyl group, enabling its use as a key intermediate or additive. It is primarily needed by manufacturers in the coatings, textiles, and specialty polymer industries seeking to develop advanced materials with low surface energy, durability, and specific chemical functionality.

Application

• As a critical fluorinated intermediate for synthesizing advanced surfactants and emulsifiers.
• As an additive in high-performance coatings and paints to enhance water, oil, and stain repellency.
• In the surface treatment of textiles, leather, and non-woven fabrics to achieve durable hydrophobic and oleophobic finishes.
• As a key monomer or modifier in the production of fluorinated polymers and resins for specialized applications.
• In the formulation of fire-fighting foams (AFFF) and other specialty chemical formulations requiring fluorosurfactants.
• For research and development in material science, particularly in creating surfaces with ultra-low surface energy.
