Quality Control

Our Catechin 3-Rhamside is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all specifications 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). Due to its sensitivity, the product should be stored under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep the container tightly sealed in a dry environment to minimize exposure to moisture.
