Quality Control

Our Olean-18-En-28-Oic Acid,3-Hydroxy-,(3B)- is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR). We provide full traceability and Certificates of Analysis (COA) are available for all shipments, ensuring compliance with your research and manufacturing specifications.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
