Quality Control

Our Potassium 2-Methyl-1-Propenyltrifluoroborate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 19F) and HPLC analysis, to ensure high chemical purity and consistent performance as a coupling reagent. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to guarantee traceability and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, this material should be handled and stored under an inert atmosphere (e.g., nitrogen or argon) in a desiccator to prevent moisture absorption and decomposition. Recommended long-term storage temperature is 2-8°C.
