Quality Control

Our Dehydro-L-(+)-Ascorbic Acid Dimer is produced and tested under a strict quality management system. Each batch is analyzed to ensure high purity and consistency, with specifications suitable for research and industrial applications. Certificates of Analysis (COA) documenting identity, purity, and related substances are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its property of being easily oxidized, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the primary container. Keep away from incompatible materials.
