Quality Control

Our Potassium Pyran-3-Trifluoroborate is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR (1H, 13C, 11B, 19F), HPLC for purity assessment, and KF titration for moisture content, to ensure it meets the high standards required for research and industrial applications. A Certificate of Analysis (COA) is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., argon or nitrogen) due to its hygroscopic (moisture-sensitive) nature. Allow the container to reach room temperature before opening to minimize moisture ingress.
