Quality Control

Our (18α,19ξ)-17α,27-Epoxy-20-(2-Methyl-1-Propenyl)-D,28,30-Trinor-22-Oxaursane-3β,19-Diol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR, MS), to ensure it meets the high standards required for research and synthesis applications. Certificates of Analysis (COA) with detailed chromatographic and spectral data are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). The compound may be hygroscopic (moisture-sensitive); therefore, the container should be kept tightly sealed in a dry environment. For long-term storage, consider storage under an inert atmosphere.
