Quality Control

Our (S)-4-Ethenyl-1,3-Dioxolan-2-One is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to meet the stringent requirements of pharmaceutical and advanced material research. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Due to its hygroscopic nature, the container should be allowed to reach room temperature before opening to prevent moisture condensation. Keep away from heat and incompatible materials.
