Quality Control

Our 5,6-Dihydro-6-Ethenyl-4-Hydroxy-2H-Pyran-2-One is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing including HPLC, GC, and NMR to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical specifications are available upon request, supporting compliance in regulated research and development environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
