Quality Control

Our Dl-2,3-Diphenyl-Succinic Acid Anhydride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
