Description

1-Butanesulfonamide, N,n-Phosphinicobis(Oxy-2,1-Ethanediyl)Bis1,1,2,2,3,3,4,4,4-Nonafluoro-n-Methyl- is a specialized fluorinated sulfonamide derivative, engineered for high-performance applications demanding exceptional chemical and thermal stability. This compound matters as a key building block and functional additive, offering unique properties derived from its perfluorobutyl segment and phosphinic acid ester linkages. It is primarily needed by R&D chemists and process engineers in the advanced materials, pharmaceuticals, and specialty chemical synthesis sectors for developing novel surfactants, polymers, and bioactive molecules.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the development of novel active pharmaceutical ingredients (APIs), particularly those requiring fluorinated motifs for enhanced metabolic stability and bioavailability.
• Specialty Surfactant & Fluorosurfactant Precursor: Used to synthesize high-performance surfactants and wetting agents for demanding applications like fire-fighting foams, coatings, and electronics cleaning fluids.
• Polymer Modification & Additive: Acts as a functional monomer or additive to impart oil-, water-, and stain-repellent properties to polymers, resins, and advanced composite materials.
• Lithium-Ion Battery Electrolyte Additive: Investigated for use as a stabilizing additive in electrolyte formulations to improve battery cycle life and safety at high voltages.
• Catalyst Ligand & Organocatalyst: Employed in the design of novel ligands for transition metal catalysis or as an organocatalyst itself in asymmetric synthesis.
• Surface Treatment & Co-Formulant: Utilized in surface treatment formulations to modify surface energy and in agrochemical formulations as a co-formulant to enhance efficacy.

Quality Control

Our 1-Butanesulfonamide, N,n-Phosphinicobis(Oxy-2,1-Ethanediyl)Bis1,1,2,2,3,3,4,4,4-Nonafluoro-n-Methyl- is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and KF titration for moisture content, to ensure it meets precise customer specifications and internal standards. Comprehensive Certificates of Analysis (COA) documenting all test results are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to the chemical structure, it is recommended to store under an inert atmosphere for long-term stability and minimize exposure to moisture.
