Quality Control

Our β-D-Glucopyranosiduronic Acid derivative is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) documenting lot-specific results 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 light-sensitive nature and propensity for oxidation, prolonged exposure to light, heat, or air should be avoided. For long-term storage, consider under an inert atmosphere.
