Quality Control

Our Potassium 1-Hexynyltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 13C) and HPLC analysis, to ensure high chemical purity and consistent performance. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept sealed under an inert atmosphere (argon or nitrogen) and at temperatures between 2°C and 8°C for long-term stability. Allow the container to reach room temperature before opening to minimize moisture ingress.
