Quality Control

Our 3-Acetyloxy-17β-Iodoandrostan-11-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and structural identity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specification results. Our quality commitment aligns with standards applicable for research and pharmaceutical intermediate use.

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 light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat and incompatible materials.
