Quality Control

Our Dimethyldiphenylphosphonium Iodide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and elemental analysis, to ensure high chemical purity and consistent performance. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your research or production specifications.

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 tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
