Quality Control

Our 9-Hydroxy-5α-Cholestan-7-One is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) with detailed chromatograms and spectral 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). Due to its hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture absorption. For long-term storage, consider using an inert atmosphere.
