Quality Control

Our Potassium 3-Benzothiophenetrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 19F) and HPLC analysis, to ensure high chemical purity and consistent performance in sensitive applications like pharmaceutical synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (argon or nitrogen) when not in use to prevent degradation. Keep away from strong acids and strong oxidizing agents.
