Quality Control

Our n-(4-[Benzoyl]Benzyl)-N,N,n-Trimethyl Ammonium Tetraphenylborate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
