Quality Control

Our (E,E)-2,4-Heptadienyldiphenylphosphine Oxide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, identity, and impurity profile.

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 nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
