Quality Control

Our Potassium 4-Ethoxycarbonyl Phenytrifluoroborate 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 consistency and reliability for critical coupling reactions. A detailed Certificate of Analysis (COA) is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage or after opening to maintain stability and purity.
