Description

Hexafluorophosphate is an inorganic anion widely utilized as a non-coordinating counterion in advanced chemical synthesis and materials science. Its primary value lies in providing excellent solubility and stability in non-aqueous systems, which is critical for high-performance applications. This compound is essential for manufacturers and researchers in the battery, catalysis, and specialty chemical industries seeking reliable ionic components.

Application

• As a key electrolyte salt (e.g., LiPF6, NH4PF6) in lithium-ion batteries for energy storage and electric vehicles.
• As a non-coordinating counterion for catalysts in organic synthesis and polymerization reactions.
• In the formulation of ionic liquids for specialized solvents and electrochemical applications.
• As a precursor for surface treatment agents and in the production of specialty fluorine compounds.
• In analytical chemistry as a reagent for ion-pair chromatography.
• For research and development in advanced material science, including conductive polymers.

Quality Control

Our Hexafluorophosphate products undergo rigorous quality testing to ensure compliance with industry standards and customer-specific requirements. We implement strict analytical protocols to control purity and critical impurity profiles, such as moisture and free fluoride content. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature and reactivity with strong alkalis, store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep the container tightly sealed under an inert atmosphere (e.g., argon or nitrogen) for long-term stability.
