Quality Control

Our Chromanol 293B is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and development purposes. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee traceability and consistency.

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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants.
