Quality Control

Our n-[4-Methyl-7-Methoxycoumarin]-N,N,n-Tributylammonium Tetraphenylborate is manufactured under controlled conditions and undergoes rigorous quality testing to ensure compliance with stringent in-house specifications. Each batch is analyzed using advanced techniques like HPLC and NMR to confirm identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
