Quality Control

Our Potassium But-3-Enyltrifluoroborate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 13C) and HPLC analysis, to ensure high chemical purity and consistent performance in sensitive coupling reactions. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, this material should be handled and stored under an inert atmosphere (argon or nitrogen) in a desiccator to prevent moisture absorption and decomposition. Recommended long-term storage temperature is 2-8°C.
