Quality Control

Our 5,5-Diphenyloxazolidine-2,4-Dione is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing specific results for identity, purity, and impurities is provided with every shipment. We adhere to cGMP principles where applicable to guarantee traceability and batch-to-batch consistency.

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 after opening to prevent moisture absorption, which may affect stability and performance. Keep away from incompatible materials.
