Quality Control

Our Ppo21 is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, NMR, and elemental analysis, to confirm identity and purity. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

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