Description
Tetraethylammonium tetrafluoroborate (CAS 429-06-1), often abbreviated as TEATFB or , is a quaternary ammonium salt widely utilized as a supporting electrolyte in electrochemical studies and applications. Composed of the tetraethylammonium () cation and the tetrafluoroborate () anion, it offers good solubility in polar organic solvents like acetonitrile, DMF, and DMSO, coupled with a wide electrochemical potential window where its ions are relatively inert. These properties make TEATFB an excellent choice for providing ionic conductivity in non-aqueous electrochemical systems, such as cyclic voltammetry, electrolysis, battery research, and supercapacitor development. As a reliable supplier, we offer high-purity TEATFB suitable for demanding electrochemical applications.

Tetraethylammonium tetrafluoroborate is primarily used in:
- Electrochemistry: As a supporting electrolyte in non-aqueous systems (e.g., using acetonitrile, DMF, DMSO as solvents) for techniques like cyclic voltammetry, chronoamperometry, and preparative electrolysis, providing necessary conductivity without interfering with the reaction under study.
- Energy Storage Research: Component in non-aqueous electrolytes investigated for lithium-ion batteries, sodium-ion batteries, and electrochemical double-layer capacitors (supercapacitors).
- Ionic Liquid Synthesis: Used as a precursor or component in the preparation of certain ionic liquids.
- Organic Synthesis: Occasionally employed as a phase-transfer catalyst or as a source of tetrafluoroborate ions.

Packaging and Transportation
Our Tetraethylammonium tetrafluoroborate is packaged in tightly sealed containers, typically bottles or jars, to protect it from atmospheric moisture due to its hygroscopic nature. Standard transportation procedures for non-hazardous or minimally hazardous chemical solids are followed to ensure safe and compliant delivery.
Storage
Store Tetraethylammonium tetrafluoroborate in tightly sealed containers in a cool, dry place. Protect from moisture. For high-purity grades, storage in a desiccator or under an inert atmosphere may be recommended to maintain low water content.
