Quality Control

Our 1,5-Naphthalenebis(Trifluoromethanesulfonate) is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. We employ advanced analytical techniques including HPLC, NMR, and GC-MS for comprehensive characterization. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition.
