Quality Control

Our 2-o-Ethyl-L-Ascorbic Acid is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including HPLC, IR, and residual solvent analysis. A Certificate of Analysis (COA) detailing purity, identity, and specific impurities is provided with every shipment 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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption. For long-term storage, consider using desiccants or storing under an inert atmosphere to minimize oxidation.
