Quality Control

Our 17-Spiro(5,5-Dimethyl-1,3-Dioxan-2-Yl)Androsta-1,4-Diene-3-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting full specifications are available for every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
