Quality Control

Our Rac Secoisolariciresinol is produced and controlled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification (IR, NMR), purity assay (HPLC), and impurity profiling to ensure it meets the high standards required for research and development. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); therefore, containers should be kept sealed under an inert gas blanket after opening to maintain stability and prevent degradation.
