Quality Control

Our Trimethylphosphonium Tetrafluoroborate is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay (NMR/HPLC), identification (IR), and impurity profiling, to ensure it meets the high-purity standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product must be stored in a cool, dry place, ideally under an inert atmosphere such as nitrogen or argon to prevent degradation. Recommended long-term storage temperature is 2-8°C. The container should be kept in a well-ventilated area.
