Quality Control

Our 3,4-Diethyloxolane-2,5-Dione is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including HPLC, GC, and NMR analysis, to confirm identity, potency, and impurity profiles. Certificates of Analysis (COA) documenting full specifications are available upon request, supporting compliance in regulated applications.

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 tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
