Description

n-Butyl-1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-Heptadecafluoro-1-Octanesulfonamide is a high-value perfluorinated sulfonamide derivative, prized for its unique combination of extreme hydrophobicity and oleophobicity imparted by the long perfluoroalkyl chain. This compound serves as a critical advanced intermediate for synthesizing specialized surfactants, surface modifiers, and polymers with exceptional chemical and thermal stability. It is essential for R&D and production in industries demanding high-performance materials, such as advanced coatings, electronics, and specialty chemicals.

Application

• Fluorinated Surfactant & Polymer Intermediate: A key building block for synthesizing next-generation fluorosurfactants and fluoropolymers used in high-performance coatings and films.
• Surface Modification Agent: Imparts oil, water, and stain repellency to textiles, leather, paper, and non-woven fabrics.
• Electronics Industry: Used in the formulation of specialty chemicals for electronics, including anti-fingerprint coatings for displays and moisture-resistant treatments for components.
• Fire-Fighting Foams (Historical/Research): Served as a precursor in the development of certain fluorosurfactants for aqueous film-forming foams (AFFF). Current applications focus on research into alternative formulations.
• Specialty Additives: Functions as an additive in lubricants, inks, and coatings to enhance surface slip, reduce friction, and improve chemical resistance.
• Pharmaceutical & AgroChemical Intermediates: Utilized in research for creating novel compounds with modified bioavailability and stability.
• Material Science R&D: Employed in academic and industrial research to develop new materials with tailored surface properties and low surface energy.
