Quality Control

Our Potassium (2-Methoxyethyl)Trifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 13C), HPLC, and elemental analysis, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all specifications and test results. Our production adheres to cGMP guidelines where applicable, ensuring reliability for critical research and scale-up processes.

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, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) after opening. Recommended long-term storage temperature is between 2°C and 8°C. Keep away from strong acids and strong oxidizing agents.
