Quality Control

Our (3S)-3-Diethylamino-3-Ethenyl-Oxolan-2-One is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity, essential for sensitive synthetic applications. We provide comprehensive Certificates of Analysis (COA) with each batch, detailing key parameters such as chiral purity (enantiomeric excess), chemical purity (by HPLC), and identity confirmation. Our quality systems are designed to meet the rigorous standards required for pharmaceutical R&D and other high-value chemical synthesis.

Storage

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