Description

Tetrabutyl Phosphonium Salt With 1,1,2,2,3,3,4,4,4-Nonafluoro-1-Butanesulfonic Acid(1:1) is a high-performance, non-nucleophilic ionic liquid salt that combines a tetrabutylphosphonium cation with a perfluorinated sulfonate anion. This unique structure provides exceptional thermal stability, low volatility, and high ionic conductivity, making it a critical material for advanced electrochemical and catalytic applications. It is primarily sought by researchers and manufacturers in the electronics, energy storage, and specialty chemical synthesis sectors for developing next-generation materials and processes.

Application

• Electrolyte Additive for Lithium-Ion Batteries: Enhances ionic conductivity and thermal stability of electrolytes, improving battery safety and performance at high temperatures.
• Catalyst for Organic Synthesis: Acts as a highly effective, recyclable phase-transfer catalyst or reaction medium for fluorination and other demanding organic transformations.
• Ionic Liquid Solvent: Serves as a green, non-volatile solvent for electrochemical studies, separations, and specialized material processing.
• Antistatic Agent for Polymers: Incorporated into engineering plastics and films to impart durable antistatic properties.
• Intermediate for Specialty Chemicals: Used in the synthesis of advanced surfactants, lubricants, and other fluorinated compounds.
• Research & Development: A key reagent for academic and industrial R&D in materials science, electrochemistry, and green chemistry.

Quality Control

Our Tetrabutyl Phosphonium Nonafluorobutanesulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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 hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under a dry inert atmosphere for long-term storage to prevent degradation.
