Quality Control

Our 3α,16β-Bis(Acetyloxy)-5α-Androstan-17-One is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity suitable for pharmaceutical research. Quality is verified through comprehensive analytical techniques including HPLC, NMR, and mass spectrometry. A detailed Certificate of Analysis (COA) confirming identity, purity, and impurity profile is provided with each shipment to support your regulatory and R&D 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.
