Quality Control

Our Lithium Tetrakis(Pentafluorophenyl)Borate-Ethyl Ether Complex is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high reactivity. Each lot is analyzed to confirm identity, purity, and the absence of critical impurities that could impact catalytic performance. A comprehensive Certificate of Analysis (COA) detailing NMR, elemental analysis, and assay results is provided with every shipment to support your R&D and production quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (argon or nitrogen) to prevent decomposition. Keep away from heat and incompatible materials.
