Quality Control

Our Peonin Chloride(Sh) is manufactured and handled under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including identification (IR, UV-Vis), purity assay (HPLC), and impurity profiling to ensure it meets the high standards required for research and industrial applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; prolonged exposure to air, moisture, or light may lead to degradation. Keep the container tightly sealed in a desiccated environment when not in use.
