Quality Control

Our 8,8'-Bieckol is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods (IR, NMR). We ensure compliance with relevant standards for research-grade materials. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This product is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). Keep container tightly sealed in a desiccated environment to minimize moisture uptake.
