Quality Control

Every batch of 3β,17-Bis[(Trimethylsilyl)Oxy]Pregn-5-En-20-One o-Methyl Oxime is manufactured and tested under strict quality management systems to ensure high purity and batch-to-batch consistency. Our products undergo rigorous quality testing, including advanced chromatographic analysis, to ensure compliance with industry standards. Certificates of Analysis (COA) documenting purity, identity, and impurity profiles are available upon request.

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 storing under an inert atmosphere.
