Quality Control

Our 2-Methylbutyric Acid Dodecahydro-1B,3A-Dihydroxy-8C-Methyl-6-Methylene-7-Oxo-3H-Oxireno[2,3]Azuleno[1,8-Bc:4,5-B']Difuran-5-Yl Ester is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and MS, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing batch-specific results are available upon request, providing full traceability and compliance data for your regulatory needs.

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 light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation to maintain stability and purity. Keep away from heat and incompatible materials.
