Quality Control

Our Dl-Phenylsuccinic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral purity assessment, to ensure it meets precise specifications for critical applications. Certificates of Analysis (COA) detailing identity, assay, impurity profile, and physical characteristics are provided and available upon request, supporting compliance in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
