Quality Control

Our Dehydroascorbic Acid is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR), to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) documenting all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C for long-term stability. Allow the container to reach room temperature before opening to minimize moisture condensation.
