Quality Control

Our 3β,17,20-Trihydroxy-22,25-Epoxylanosta-7,9(11)-Dien-18-Oic Acid γ-Lactone is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR), to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent product degradation. For long-term storage, consider desiccant use.
