Quality Control

Our Potassium Benzyltrifluoroborate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for demanding synthetic applications. Each lot is analyzed to confirm identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing specifications and test results is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
