Quality Control

Our Potassium 3-Ethoxycarbonyl Phenyltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR (1H, 13C, 19F, 11B), HPLC for purity, and KF titration for moisture content, to ensure it meets the high standards required for sensitive cross-coupling reactions. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and consistent performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, it is recommended to handle the material under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize exposure to ambient humidity. Optimal storage temperature is 2-8°C.
