Description

n-Ethyl-1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-Pentadecafluoroheptane-1-Sulphonamide is a high-purity, fully fluorinated sulphonamide derivative, valued for its exceptional chemical and thermal stability imparted by the perfluoroalkyl chain. This compound serves as a critical advanced intermediate in the synthesis of specialty surfactants, polymers, and surface-modifying agents. It is primarily sought by R&D and production teams in the fluorochemical, pharmaceutical, and advanced materials sectors for developing products with unique hydrophobic, oleophobic, and low surface energy properties.

Application

• Fluorinated Surfactant & Polymer Synthesis: A key building block for creating high-performance, oil- and water-repellent surface-active agents and fluoropolymers.
• Pharmaceutical Intermediate: Used in the research and development of novel active pharmaceutical ingredients (APIs) that require enhanced metabolic stability and lipophilicity.
• Advanced Material Modifier: Imparts permanent surface modification to textiles, coatings, and composites, providing stain resistance and easy-clean properties.
• Electronics Industry: Potential application in the formulation of specialty fluids for electronics cooling or as a precursor for dielectric materials.
• Firefighting Foam Precursor (Legacy/Research): May be used in research for formulating high-performance aqueous film-forming foams (AFFFs), with a focus on next-generation, environmentally conscious chemistries.
• Laboratory Reagent: Serves as a specialized reagent in organic synthesis and material science research for introducing fluorinated sulphonamide functionalities.
