Description

n-(3-Diethoxyphosphorylpropyl)-n-Ethyl-1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-Heptadecafluoro-Octane-1-Sulfonamide is a high-value fluorinated sulfonamide derivative with a phosphonate ester functional group. This unique molecular architecture combines the exceptional hydrophobicity, oleophobicity, and chemical resistance of a long perfluoroalkyl chain with the versatile reactivity of a phosphonate ester. It is primarily sought after for its ability to impart surface-modifying properties in advanced material formulations. Industries involved in specialty coatings, surfactants, and high-performance polymers utilize this compound to achieve specific functional characteristics.

Application

• Fluorinated Surfactant Intermediate: A key building block for synthesizing high-performance surfactants and emulsifiers used in demanding environments, such as fire-fighting foams (AFFF) and specialty cleaning formulations.
• Surface Modifier for Coatings: Imparts oil, water, and stain repellency to textiles, leather, paper, and non-woven fabrics, creating durable protective finishes.
• Polymer Additive: Incorporated into polymers and resins to enhance surface properties, reduce surface energy, and improve chemical resistance in final products.
• Lithography and Electronics: Potential use as a photoresist additive or surface-leveling agent in semiconductor manufacturing due to its fluorinated structure.
• Pharmaceutical & Agrochemical Intermediate: Serves as a sophisticated synthon for introducing fluorinated sulfonamide motifs into bioactive molecules, enhancing their metabolic stability and lipophilicity.
• Specialty Material Synthesis: Used in research and development of novel fluorinated materials, including liquid crystals, membranes, and catalysts.
