Quality Control

Our Dichloro(Hexadecyloxy)Phosphine Oxide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles 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, and 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) after opening to prevent hydrolysis and degradation. Keep away from strong bases and oxidizing agents.
