Quality Control

Our Lithium Tetrakis(Pentafluorophenyl)borate is manufactured under strict quality protocols to ensure batch-to-batch consistency and high performance in sensitive catalytic applications. Each lot undergoes comprehensive analytical testing, including NMR and elemental analysis, to verify identity and purity. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; ensure containers are sealed immediately after use to exclude moisture and air.
