Quality Control

Our Lithium Tetrakis(Pentafluorophenyl)Borate-Ethyl Ether Complex is manufactured under strict quality protocols to ensure batch-to-batch consistency and high reactivity. Each lot undergoes comprehensive analysis, including NMR spectroscopy for structural confirmation and titrimetric or ICP-MS methods for precise assay determination. A detailed Certificate of Analysis (COA) documenting purity, solvent content, and key impurity profiles is provided with every shipment to support your quality assurance and R&D documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept sealed under an inert atmosphere (argon or nitrogen) when not in use. Handle and store away from strong oxidizers.
