Quality Control

Our Potassium Cyclopentoxymethyltrifluoroborate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for research and development. We provide comprehensive analytical data, including NMR (¹H, ¹³C, ¹¹B, ¹⁹F) and HPLC analysis, with each shipment. Certificates of Analysis (COA) detailing purity and impurity profiles are available upon request and are compliant with standard industry practices for fine chemical sourcing.

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 tightly sealed under an inert atmosphere (argon or nitrogen) and desiccated to maintain product integrity. Recommended long-term storage at 2-8°C.
