Quality Control

Our Potassium (Z)-4-Phenylbutenyl-1-Trifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (¹H, ¹³C, ¹¹B, ¹⁹F) and HPLC analysis, to ensure high chemical purity and isomeric integrity. Certificates of Analysis (COA) with full characterization data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (argon or nitrogen) due to its hygroscopic (moisture-sensitive) nature. Allow the container to reach room temperature before opening to minimize moisture ingress.
