Quality Control

Our Oleanonic Acid Benzyl Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR, MS), to ensure it meets the stringent requirements of research and development applications. Certificates of Analysis (COA) detailing batch-specific results are provided with 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). This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term storage, consider sealing under an inert gas such as nitrogen or argon in a sealed vial.
