Quality Control

Our Bis(2-Dichlorophosphinophenyl)Ether is manufactured under strict quality protocols. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong acids and organic solvents.
