Quality Control

Our 1,8-(Diphenylphosphino)Naphthalene, 99% is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure the specified purity and identity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your research and production standards.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at room temperature (15-25°C). Due to its sensitivity to oxidation, the container should only be opened in an inert glovebox or under a positive pressure of inert gas.
