Quality Control

Our Pinoresinol Diglucoside is produced under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets stringent specifications for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
