Quality Control

Our Potassium tert-Butyltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles by NMR, HPLC, and elemental analysis is provided with every shipment.

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) and protected from moisture to maintain stability and purity. Recommended long-term storage at 2-8°C.
