Quality Control

Our (3β,5α,6β,22R,24R)-6-Methoxy-3,5-Cycloergostan-22-Ol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity assays and structural confirmation, to ensure it meets the high standards required for research and synthesis. A comprehensive 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 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 using desiccants.
