Quality Control

Our Potassium Trifluoro(3-Oxocyclopentyl)Borate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 13C), HPLC, and KF titration, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed specifications are provided to guarantee the material meets your research or production requirements.

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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition.
