Quality Control

Our 5α-Cholestane-3β,6α-Diol Diacetate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR, MS), to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). The product is stable under these conditions but should be kept in a desiccator if long-term storage is required to minimize any potential moisture uptake.
