Quality Control

Every batch of (18α)-Oleana-9(11),12-Diene-3β,16α,21α,28-Tetrol is manufactured and controlled under a strict quality management system. We provide comprehensive analytical documentation, including a detailed Certificate of Analysis (COA) specifying purity (typically ≥95% by HPLC), identity confirmation (by NMR, IR, and MS), and impurity profiles. Our quality commitment ensures the material is suitable for use as a high-grade reference standard in demanding research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
