Quality Control

Our (17S,22R)-3α,6α-Epoxy-4β,5,14,17,20,22-Hexahydroxy-1-Oxo-5β-Ergost-24-En-26-Oic Acid 26,22-Lactone is produced and handled under strict quality management protocols. Each batch is characterized using advanced analytical techniques including HPLC, NMR, and mass spectrometry to ensure structural identity and high purity. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your research and compliance needs.

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 degradation. For long-term storage, consider desiccants or inert atmosphere.
