Description

1-(Nonafluorobutyl)Trifluoroethanesultone is a specialized fluorinated sultone compound, serving as a high-performance building block for advanced materials. Its unique perfluoroalkyl chain and reactive sultone group make it a critical precursor for introducing sulfonic acid functionalities into fluorinated systems. This product is essential for R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries seeking to develop novel surfactants, electrolytes, or functional monomers with enhanced stability and performance.

Application

• Lithium-Ion Battery Electrolytes: As a key precursor for synthesizing novel lithium salts (e.g., Li-FSI analogs) to enhance ionic conductivity and thermal stability.
• Fluorinated Surfactants & Polymers: For the production of high-performance, oil- and water-repellent coatings, films, and surface modifiers.
• Pharmaceutical & Agrochemical Intermediates: Used to incorporate fluorinated sulfonate groups into active ingredients to improve bioavailability and metabolic stability.
• Ion-Exchange Membranes: A monomer for developing next-generation proton exchange membranes (PEMs) for fuel cells with superior chemical resistance.
• Specialty Chemicals & Catalysts: Acts as a versatile intermediate for creating fluorinated catalysts and ligands used in demanding chemical processes.

Quality Control

Every batch of 1-(Nonafluorobutyl)Trifluoroethanesultone is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity requirements for sensitive applications like electrolyte and pharmaceutical synthesis. A detailed Certificate of Analysis (COA) confirming identity, purity, and impurity profiles is supplied with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is moisture-sensitive; keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain stability.
