Quality Control

Our p-Xylylenebis(Triphenylphosphonium Chloride) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance 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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials.
