Quality Control

Our 3β-(Trimethylsiloxy)-5α-Androstan-17-One o-Methyl Oxime is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and identity confirmation. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and compliance with your research or production requirements.

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.
