Description

n-Ethyl-1,1,2,2,3,3,4,4,4-Nonafluoro-n-(2-Hydroxyethyl)Butane-1-Sulphonamide is a specialized fluorinated sulphonamide derivative, valued for its unique combination of hydrophobic, oleophobic, and surface-active properties imparted by its perfluorinated chain. This compound is a critical intermediate for synthesizing advanced materials with low surface energy and high chemical resistance. It is primarily sought after by R&D and manufacturing sectors in the specialty chemical, polymer, and surface treatment industries for developing high-performance coatings, surfactants, and functional additives.

Application

• Fluorinated Surfactant Intermediate: A key building block for synthesizing high-performance, environmentally persistent fluorosurfactants used in firefighting foams (AFFF), coatings, and emulsion polymerization.
• Surface Modifier for Polymers: Imparts oil, water, and stain repellency to textiles, carpets, and technical fabrics when incorporated into polymer backbones or applied as a finish.
• Specialty Additive for Coatings and Inks: Enhances leveling, wetting, and anti-cratering properties in high-value industrial and architectural coatings, inks, and adhesives.
• Pharmaceutical and Agrochemical Intermediate: Serves as a precursor for bioactive molecules, leveraging the metabolic stability and lipophilicity of the fluorinated group.
• Lithography and Electronics: Potential use in photoresist materials and as a surface treatment agent in semiconductor manufacturing processes.
• Research & Development: Utilized in academic and industrial labs for exploring novel fluorinated compounds with specific surface and self-assembly properties.

Quality Control

Our n-Ethyl-1,1,2,2,3,3,4,4,4-Nonafluoro-n-(2-Hydroxyethyl)Butane-1-Sulphonamide is manufactured under a strict quality management system. Each batch is analyzed to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing key parameters such as assay (by HPLC/NMR), impurity profile, water content, and color are provided and available upon request. We support compliance with relevant global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed and under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent degradation. Keep away from strong oxidizing agents.
