Quality Control

Our (2R)-2-(3,4-Dimethoxyphenyl)Butanedioic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to ensure compliance with stringent specifications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
