Quality Control

Our (2,6-Naphthalenedimethylene)Bis(Triphenylphosphonium Bromide) is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and residual solvent analysis, to ensure it meets the high standards required for synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and consistency.

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 (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
