Quality Control

Our Menadione Semiquinone is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including purity assay and impurity profiling, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) with detailed chromatographic data (HPLC) are provided for every shipment 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 sensitivity, the product should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and maintain stability. Keep away from incompatible materials.
