Quality Control

Our α-Tocopherylquinone is produced and tested under strict quality management systems. Each batch undergoes comprehensive analysis to ensure identity, purity, and consistency, meeting the requirements for research and industrial use. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, related substances, and physical characteristics.

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 light-sensitive nature and tendency to be easily oxidized, prolonged exposure to light, air, or elevated temperatures should be avoided. For long-term storage, consider under an inert atmosphere.
