Quality Control

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

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 hygroscopic (moisture-sensitive) and easily oxidized nature, prolonged exposure to air and humidity should be avoided. For long-term stability, consider storage under an inert atmosphere.
