Quality Control

Our (3R,5R,7R,17S)-7,10,13,17-Tetramethyl-1,2,3,4,5,6,7,8,9,11,12,14,15,16-Tetradecahydrocyclopenta[A]Phenanthrene-3,17-Diol is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. All products undergo rigorous analytical testing, including HPLC, GC, and NMR, to confirm identity, purity, and chiral integrity. Certificates of Analysis (COA) detailing all specifications are available upon request. We can support development projects with custom purity grades and analytical method development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep the container tightly sealed when not in use to protect from moisture and atmospheric contamination. For long-term storage, consider storage under an inert atmosphere.
